Controling mirror movement with piezoelectric stage

  1. Feb 9, 2015 #1
    I am moving a small glued mirror (~10 gram) attached to a piezoelectric stage:
    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?
