Hi...

am new mathcad user having problem solving diffrential equations using feed back loop control in real time.

As i go through different search areas but failed to get any clue of solving control problem. Can any body give me a good suggestion for using this software for real time control programming???

A simple equation is attached, would be helpful to understand my problem.

Thanks

Aoo.... thats cool......i was wondering in loop solution for feed back but its so simple

Thanks Alan

Definately require syntex practice Well there is another thing of dual diff equation solution attached.

Need to know about error message and the way out........

Thanks

Need to know about error message and the way out........

when you call e() in the solve block twice you have to write e(t, x(t)) instead of just e(t,x).

It also helps significantly speeding up the calculations if you predefine the used derivations of Xp and lamdap.

Careful!!

Mathcad is not a "real-time" application. You may get some really nasty surprises when the system goes off to do something else.
