Abstract: In O-E stabilization turret, the stirling cooler's disturbance and axis's friction torque are both the main disturbance. Considering the traditional control methods are insufficient to restrain the above two kinds of disturbance, Kalman filter algorithm was introduced to the photoelectric stabilized turret in this paper, its role was to use the recursive algorithm to filter the system and random measurement noise. The simulation results prove it effective. Compared with the classic PID regulator, the regulator based Kalman filter can improve the stable precision from 40% to 1%. The goals to improve the stability and to overcome the noise interference are realized.
