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

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.
