Abstract

In order to overcome the deficiencies of classic control method in the disturbance rejection and robustness, the automatic disturbance rejection controller (ADRC) was introduced into the fiber optic gyro(FOG) stabilized platform. A control model for the position servo loop of FOG stabilized platform was set up. The non-linear structure of ADRC was discussed. ADRC was designed to improve the dynamic performance indexes of FOG stabilized platform. Considering the changing parameters and disturbing factors that may appear in real work, the quality of disturbance rejection and robustness of the ADRC was tested. The ADRC and PID controller were simulated in the same conditions. Simulations show that the oscillations and overshoots of ADRC was not obvious. ADRC has faster and more precise responses. ADRC is not sensitive to the changes of the model parameters.
