PID control for student 2010 edition

Hi I need to get a pid controller for a project i am completing in college , is there a pid controller that can run on this verson of labview ??

PID Controller is nothing but a mathematical calculations. My suggestions is stretch yourself and try duplicating the PID contollers into LabVIEW.
The best solution is the one you find it by yourself

Labview PID control for virtual CNC lathe

i am currently in my third year at UMIST, on the Mechanical Engineering (MEng) course. I am designing a control system for a miniaturised CNC lathe for my 3rd year project. For integration between the computer and actuators, i am planning on using Labview 7, but am currently having problems learning how to utilise the PID control toolset to create a virtual system response. I am planning on being able to input a specific transfer function for, say, a DC motor, and a ramp input, for example, and being able to view the output response as i vary the P, I and D gains. Some help with regards to the block diagram set-up for such a system would be greatly appreciated.

The best place to look for this kind of information is the shipping examples of LabVIEW. Open LabVIEW >> help >> find examples. Another good place is online. Go to Advanced Search and look in the example programs.

Am not sure why you are searching the PID terminals in DAQ assistant. Are you using any LAbVIEW PID module?

I need to maintain a temperature profile for my process.Can i use PID control for this application?

Hi all,
I need to maintain a temperature for my process.Can i use PID control vi's for this application?
I have NI-PCI 6023E DAQ board.Should I need any other hardware components???
Any help in this regard is highly appreciated.
Thanks,
radhika

Hi,
Thanks for your reply.
I do have a temperature sensor and it is read by the DAQ (NI 6023E) .
Also i have a voltage input to the program which has to be controlled in order to control the temperature.
So , I am using a PID , the output of the PID should control the Voltage input so that the temperature is controlled.
Can I give the voltage input and the temperature to the PID through the DAQ and just use one more channel in the DAQ to get the output from the PID.Will that work???
I am not sure why you have mentioned SC2345,SCB68.
Thanks,
radhika

Basic PID control for LabVIEW 7.0

I am trying to find the basic PID control VI in my LabVIEW pallet. I thought that there was some PID VI's in 6.1 but I can't seem to find them in 7.

Hi Dan,
I don't think we ever put the simple PID in the pallet. However, if you'll run the NI Example Finder (Help>>Find Examples...) and search on PID, you'll find examples that use the simple subVI.

PID control for a sinusoid

Hello,
I have written a program that takes a reference signal, and then uses a
proportional control to synthesize a similar signal in a wire coil. I
modulate the duty cycle of the counters of a PCI 6224 card. One counter
goes to the positive side of an H Bridge, and the other to
the negative. I'm getting decent results for reference frequencies of
about a hz, but if I go below that I start seeing more interesting wave
forms (the funkiness appears when the waveform crosses zero). I am
questioning whether adding integral or differential controls are liable
to improve matters given the time dependence of the system, and how to
best apply them if appropriate.
Attached are my program and the results it gives for several
frequencies. Most of the missing VIs are those that record the data to
file. The other is the proportional controller from the PWM Counter
Output example, taking the reference signal as its setpoint. (It also
adds .5 to the duty cycle from the P output. If at the setpoint, I want
the current in the coil to remain constant)
Thanks,
Elliot

Hey, are you using the PID toolkit in LabVIEW? If so, this link: http://www.ni.com/pdf/manuals/372192a.pdf, discusses using interregnal and derivative terms. It is possible that your system just can't do frequencies below that. Personally, I have found the best way to figure this stuff out is to just try. Also, consider using the PID gain scheduling VI. This will let you have different P, I , & D terms based on an input. I have found that a very useful tool.
Hope this helps!

Activations for Creative Cloud for student teacher edition

I need to upgrade my software and was looking into creative cloud. I am a teacher and would get the full creative cloud package. Is that a normal activation code that would work on two computers (my desktop and my teacher laptop)?
Second I have lightroom 4 and photoshop cs5 extended when downloading will that sync with my previous catalogs with all prior settings (adjustements, ratings, etc.)?

Hi Bledererphoto13,
If you purchase a student teacher version you typically have to provide some kind of proof of eligibility, the required codes and process varies slightly depending on whether you purchase from Adobe direct or a reseller. The license allows you to use the software on two computers.
The Lightroom 4 catalog gets converted to 5 and should retain everything http://forums.adobe.com/message/5430081
I'm not sure about the settings for Photoshop CS5 to Photoshop CC, I know it does it between CS6 and CC. You could post in the Photoshop forum about it.

Serial number is invalid when trying to install Creative Suite 6 (Student/Teacher Edition) on my new mac?

I have deactivated CS6 on my old laptop, but every time I try to enter the serial number to re-activate it tells me that it is invalid. Is there a period of time that I have to wait before it becomes able to be activated again? It's been about 24 hours. Or could the problem be that it was previously installed on a PC, but now I have upgraded to a mac? Is there any way to fix this? Please help! Thank you!

Normally a PC serial number is not valid for a Mac version. I don't know if the following holds for Student/Teacher editions though there should be something similar...
Change product platform or language
You can swap languages/platforms for a latest version product if you follow the instructions at the following link:

Can I install CS5 student teacher edition without using the disk on my 2nd computer as I do not have a disk drive

I have CS5 student and teacher edition. I have a CD. I want to install it onto my mac book pro (2nd computer), can I do this without using the disk.

Thanks very much, well I'm still struggling.
The link kind of worked [took a couple of hours ] but then I wasn't able to fully install it, it said it was partially installed and I didn't know where to go from there. A red disk appeared on my desk top, I clicked it and another window appeared but then I couldn't do anything with it. It said I had to access the download manager but I don't know what a download manager is, it certainly isn't where my documents download to.
My original CD is for student teacher edition which I still fall under, I have a serial number for that edition.
If you are able to shed any further light on this I would be very grateful.

Throttle body PID control using pulse width modulation

Hello all,
I am trying to do a PID control for a throttle body (using pulse width modulation) for a set value of feedback voltage. The process variable is the pulse width duty cycle. The throttle body is expected to be fully open at a feedback voltage of 5V and pulse width duty cycle of 42.5%. When I use the highlight execution using the attached file, I can see the throttle body fully open (the values observed are: PID output 42.5 %, feedback voltage approximately 4.7V). However, when the highlight execution is unclicked, the throttle body flutters in the closed condition (still PID output 42.5%, feedback voltage approximately 0.9 V). Can any one please help by suggesting any modification to this attached file to make this throttle body respond to the set value of feedback voltage.
Many thanks
Ajith

Throttle body control using PWM technique - PID.vi ‏525 KB

How did you determine your P, I, and D gains? If you have not tuned your controller, you'll get poor performance. Running with execution highlighting will slow down the execution, which will change the effect of the gains. I would start with pure proportional control (I and D = 0) with a small proportional gain, and see if it responds in approximately the way you want. If so, then your code is probably correct, and you just need to do a full tuning to get good performance. There are many resources available on the web, on this forum and elsewhere, for PID tuning. Note that since your code uses a simple PID example, and not the one from the PID toolkit, the gains do not have the units that are used in many tutorials so you'll have to correct the calculations to compensate.

CS5 Student & Teacher Editions & Commercial use (in Australia)

specifically student editions not educational version.
I know that in CS4, commercial use is only valid in the USA.
It looks like the older "education version" is no more in CS5 and is replaced? by "Student & Teacher Edition".
I have read in the FAQ from the USA Adobe website that this is allowed for commercial use:
http://www.adobe.com/education/students/studentteacheredition/faq.html
I have also seen the UK Adobe site that it is allowed for commercial use:
http://www.adobe.com/uk/education/students/studentteacheredition/faq.html
the image is broken on this link. is this just a template that has been copied over from the USA website? or is this the official thing?
I am from Australia and the FAQ has not been updated and still shows information for CS4.
clicking on FAQ from this link on the australian site of Adobe links to the CS4 FAQ:
http://www.adobe.com/ap/education/solutions/students/studentteacheredition/
which is this link: http://www.adobe.com/ap/education/students/studentedition/faq.html
though after some digging I have found the Australian link to the new FAQ but it also has a broken image and im not exactly sure if its the read thing or just a template again:
http://www.adobe.com/ap/education/students/studentteacheredition/faq.html
they all state:
Can a student or teacher use the Adobe Student and Teacher Edition software for commercial use?
Yes. Those who purchase this product can use it for personal as well as commercial use.
I havent found anything about "only in north america" stuff.
anyway, i would assume that any purchase of CS4 now would have a free upgrade to CS5, right?
If i purchase CS4 student edition (which here in australia isnt allowed for commercial use) and then get a free upgrade to CS5 (student & teacher edition (i would assume this would be the version CS4 student edition would get for the free upgrade? and assuming that commercial use of CS5 is now allowed in Australia for Student & Teacher Edition) would that mean that I can now use my CS4 student edition that was originally not allowed for commercial use then now be allowed for commercial use when upgraded to CS5 student & teacher edition?
I hope that makes sense and doesnt confuse too much.
I also posted up a thread about my eligibility if im a student that has finished classes and waiting to just graduate now. I was wondering if I may still be considered an eligible student to purchase.

Hi, I think I have found an answer to this but I would still like to have it confirmed by someone from Adobe (please).
I found a post at http://www.hellophoto.co.nz/showthread.php?3223-Lightroom-3-is-now-out&p=32387#post32387
Where someone in the forum says they contacted Adobe NZ about this:
I asked Adobe about the answer to the question about commercial useage - this was the reply I got
This has caused some confusion as we have recently
changed the policy around this. You are correct that it used to just be
in the US however in CS5 we have changed this to be the case for all
regions.
In NZ Student and Teacher licenses can be used
for commercial use both during study and after students or teachers have
finished/left. I.e. a teacher can do freelance work on the side and
still be eligible for the student and teacher pricing.
When the next version of CS is released students
who have finished their studies or teachers who have left the institute
can upgrade to a commercial version at the upgrade price.
We do not require them to upgrade so if they wish
they can stay on CS5 indefinitely, when they do decide to upgrade they
will need to purchase a commercial license. We have tiered upgrade
pricing though so it works out cheaper for them if they do upgrade
straight away.
The main condition for Student and teacher is
that it is installed on a private computer so cannot be installed at an
institute (school, uni or poly). Instead, educational institutions must
purchase the Education version.
Student and teacher licenses are for home use on
private computers for educational or commercial purposes for that one
person. There is no serial number in the box and verification is
required.
Educational licenses are for use on an education
institute’s (schools, unis or polys) computers, this is for educational
use only and does not include commercial use. Single teachers should not be purchasing this type of license, the only people who should be buying educational licenses are educational institutions.
I teach Photoshop and Illustrator at a Uni in Australia and would really like to be able to tell students if they can use the Student and Teacher editions for commercial use - If the above is true I think this is a very clever move by Adobe but it would be really good if they made it a bit clearer.

I have a big delay in my real time pid control

hi ,
since i don't have a digital input module i tried to use the serial port RS232 on my Crio to read the data from an absolute encoder in order to perform PID control for a dc motor, but the problem is that the data took too match time to be read; there is a big delay between the first read position and the next one,and when i change the slide controller the indicator took time to change, although it should be instantinouse, here is
a snapshot of my vi.
please i need help.

Hi Moho,
Looking at your code I see a couple of things that might be causing the issue. How long is the delay that you are experiencing? You are trying to transfer 2000 bytes every loop which will cause some delay. You also have a lot of mathematical operations that can take time between loop iterations. Also what is the VI that you have manipulating your waveform? Have you looked into the PID VIs?

PID-Control (Tank Level)

Hi!
I want to realize a PID-control for a tank level. I've already looked at all related examples in LabVIEW, but I have a general question:
Where is the measured value brought into the process (where would I connect the DAQ to the control-loop)?? I can't figure out how it's done in the examples (there is always an "initial value" outside the while-loop)....
Would be great to get some answers!

Generally you take the DAQ value and feed it into the PID as the process variable. The examples store the process variable in a shift register in order to simulate a system in which the current value depends on the previous value, but in a real system the physics of the system handle that for you. For example in a tank control system, the tank itself holds some amount of liquid, which doesn't change by a large amount within one sample period. To simulate that properly you need to store a value equivalent to the liquid volume in a shift register.

What do I have to submit for proof of eligibility to use Adobe Acrobat Pro XI - Student Teacher Edition?

Our organization purchased ten Acrobat Pro XI - Student Teacher Edition. The side of the box says "STOP - Proof of eligibility MUST be provided..." but it does not offer a specific link or form that needs to be completed. We are a small organization and this software was purchased for our teaching staff. Please provide a link for assistance.
