i am trying to tune PID in my permanent magnet synchronous motor. there has 3 PID controller which is to control speed and direct and quadrature current. any best technique to tune this PID?

Hi Al,
The other approach is the following:
1. Do frequency response estimation - inject ac sweeps on d and q voltage and estimate frequency response from vd and vq to id, iq, and motor speed. See here on how to do frequency response estimation.
2. Once frequency response data is available, use system identification and identify a state space model from vd,vq to id,iq,speed
