Completely GUI for Nonlinear control system

Question

Hi,
   I am working on nonlinear control system particularly for linearization part.My problem is that i have 4-5 nonlinear equation like that 2*x1^2+3*x1*x2+x3 - 2*u.I want to make GUI in which User chage fully equation with constat,co-efficient.For that i use string and it is working.Linearization is process that gives us A,B,C,D matrix which use for linear control sysytem.
In Labview Control design toolbox have linearization .vi which solve.But in this make subsystem in simulation loop.which not make fully GUI.I also use mathscript but no command find.
Finlly in MATLAB have command Jacobian,Diff. Is there command in Mathscript for Differentiate equation.
OR how i call .m file in labview if i made code in labview.

Answer 1

If you plan on using a desktop PC for control type applications, then your best option in terms of performance will be with a Real-Time operating system. Windows is not deterministic for many reasons. Determinism involves the ability to respond to an event within a specified amount of time with an acceptable amount of error (jitter). First of all, Windows is not deterministic because it has to service mouse and keyboard events, as well as anti-virus software, automatic updates, etc.
You can, however, convert an existing desktop PC to a Real-Time target with a Real-Time OS and use it for your control type application with the deterministic behavior of PXI, Compact FieldPoint, and other Real-Time targets. Check out this link for more information.
On a side note to a previous reply, using the LabVIEW Real-Time module on Windows XP won't make your application deterministic. Your best bet, as others have noted, is to use the LabVIEW RT Module on an RT OS with good RT programming practices (avoiding memory allocations, etc.).
