Abstract

Attenuation of disturbance torque fluctuation is a significant way for improving the performance of Single Gimbal Control Moment Gyro (SGCMG) gimbal servo system. Based on the analysis of the causes and influences of the disturbance torque, fuzzy logic controller combined with acceleration disturbance observer is proposed to prevent wide margin disturbance torque fluctuation. Simulation results show that the proposed strategy attenuates wide margin disturbance torque fluctuation much better than the conventional method.
