Abstract
A mirror pointing controller has been designed for a high-speed beam steering mirror which exhibits a highly resonant time-varying system function. Instead of attempting to continuously control the mirror pointing trajectory, the control algorithm constrains the mirror pointing angle only at the discrete strobe occurrences during the pulsed experiment by modifying the input waveform. Adaptation of the controller parameters to values which satisfy a mirror response error criteria is done during the interval between pulses. Pointing errors on the order of 3% of full scale have been measured.
