Abstract

In view of the requirements of isolating disturbances and stabilizing optical axis of high-precision gyro stabilized platform, a double-axis stabilized platform system centering on the flexible gyro was designed. The gyro stabilized platform’s structure were introduced and it’s error sources was analyzed. In order to eliminate the steady-state angle error which occurs in rate gyro feedback and traditional PID control scheme, a sliding mode variable structure control scheme is presented. The results show that the gyro stabilized platform accuracy can improve 50% above after using sliding mode variable structure control. 〓〓〓
