Adaptive robust control over high-performance VCM-FSM
摘要
Abstract
In order to improve the performance of the aviation photoelectrical stabilized platform ,an adaptive robust control (ARC)-based VCM-FSM (voice coil mode-fast steering mirror) was proposed . Firstly ,the current loop was adopted into electric circuit to simplify the complex model of motor into a first-order model and guarantee the stablity of output torque of the motor .Secondly ,on the basis of conventional PD controller ,ARC algorithm was introduced to control the position of VCM-FSM and restrain disturbance . Finally performance tests were conducted in bandwidth test experiment , disturbance restrain experiment ,stabilization experiment of visual axis and robust experiment .As comparison ,experimental results of DOB-based VCM-FSM and PCT-FSM were offered at the same time .As compared with the DOB-based VCM-FSM , parameter robust characteristic of proposed control method is stronger .Meanwhile ,as compared with traditional PZT-FSM ,it also exhibits longer travel range ,much simpler driving circuit ,and lower power consumption while the precision of LOS stability remains almost the same .Moreover ,visual axis stabilization precision of ARC-based VSM-FSM within 5 μrad (RMS ) can all be achieved under disturbance influence of any frequency within 80 Hz .This outstanding performance can be maintained at the temperature of -40 ℃ to 50℃ ,w hich is superior to the DOB-based VCM-FSM and can fulfill the requirements of a high precision aviation photoelectrical stabilized platform . Thus it has high practical value on improving anti-disturbance performance of control system for optoelectronic stabilizing platform of aviation .关键词
