In view of the poor image stabilization of the EO platform based on the moving vehicle, an effective method is proposed, reducing gyro sampling frequency and system control cycle, adding a current loop in the driving circuit, and adding an expanded state observer to observe and compensate the disturbance in the control loop. The effectiveness of the method is verified from swing table test and actual moving vehicle test. Under the three axes swing condition at 3 °、 2s, the dual axis stabilization of the EO platform is better than 0.15 mil (1σ). Under the condition of earth rock pavement and at the vehicle speed of 15~30 km/h, the dual axis stabilization of EO platform is better than 0.2 mil (1σ). Based on the traditional PID algorithm, this method is simple and effective, it can achieve obvious improved stability only by little optimization. This method is also applied on the shipborne and airborne EO platforms.
