I am moving a small glued mirror (~10 gram) attached to a piezoelectric stage:
http://www.physikinstrumente.com/product-detail-page/s-330-300700.html
The mirror moves back and forth for a few milliseconds using a PID control loop, the range is about 2mrad.
I want to increase the angular amplitude and maximal speed of that movement, for that I want to tweak the PID coefficients.
1) Can someone tell me using control theory how to calibrate them?
2) The entire system resonant frequency is about 2kHz, should I stay away from it or try to use it?
