PID controller for vector control

[Billstrong]

Dear all,

I am working on vector control recently using labview's reference

http://decibel.ni.com/content/docs/DOC-2386

things are all right until I come to the PID controller for Id and Iq, can anyone tell me how this gains are derived?Do you use manul tuning to obtain these gains?

I have searched some papers and find out the  motor model for vector control is complicated and nonlinear, is it possible to use matlab to derive these gains?

It would be very helpful if you can provide me some reference or share you experience on this area.

so, what you wanna talk is how to deciede the gain parameters for PID control, right ?  that is another topic about control theroy , you'd better google some related documentation for more details.. and about the analysis tools, matlab, labview, anyone is ok.

Hi Bill

Interesting project. I was just wondering, what sort of NI hardware are you going to use?
