Abstract

A 1-kHz control system for precision position control of a two-axis gimballed mirror is presented. The control system is unique in that it uses the state estimator's position estimates to excite the Inductosyn position transducers. Also presented is a concise algorithm for proximate time optimum control within available motor torque (or alternatively, maximum gimbal acceleration) and maximum allowable gimbal rate. The newly developed Inductosyn excitation/reduction scheme and proximate time optimum algorithm are successfully demonstrated on hardware designed, constructed, and tested by Contraves USA, where accuracies better than 4 arc seconds were measured.
