ADAPTIVE CONTROL APPROACH FOR PERIODIC RATE RIPPLES IN INERTIAL GUIDANCE TEST EQUIPMENT

Yuansheng Zhang

Abstract

The rate performance of inertial guidance test equipment (IGTE) affects the performance testing of inertia devices and navigation systems. Periodic rate ripples caused by periodic disturbances have a great effect on the rate performance of rotation test tables. The mechanism caused by the rate ripple in IGTE is analyzed. Based on the nonlinear self-adaptive control system approach, a control system scheme is proposed to eliminate the period disturbances for its uncertainty. Experimental results show that the periodic rate ripple can efficiently be controlled.
