POLL: control loops
 

For those of you who use feedback control, what algorithms do you use? PID/P/PI/PD? Digital? Fuzzy logic? etc? How fast do you run your loop? What special problems have you encountered? What are you using it for? Speed control? Position control? Load compensation on manipulator?

Maybie this deserves its own thread, but i am going to put it in this semi-related thread anyway. For those teams that have implemented any sort of controller that has a Integrl ter, how do you handle setpoint changes?

I have not yet tested a PID loop, though I have researched and coded one. Could you explain what different ways there are to handle setpoint changes? Seems to me there is only one way...
