【Abstract】 To suppress the disturbance in the electro-optical stabilized platform, a filtering method and a control strategy is proposed in this paper. The electrical structure and principle of the electro-optical stabilized platform is introduced and the disturbance factors in the electro-optical stabilized platform is analyzed. The Kalman filter is designed for the disturbance from sensor, and an active disturbance rejection speed controller is designed for the torque disturbance and rate disturbance. The experimental results show that, the technical requirements is satisfied by using Kalman filter and the active disturbance rejection speed controller.更多还原
