摘要：
Photoelectric stabilization platform is the eye of the aircraft. At present, the two-axis two-gimbal photoelectric platform is widely used in military, commercial and scientific applications due to simple mechanism, low cost and small size. However, the stability performance of the outer gimbal will be reduced at large pitching angle. In this paper the reason was analyzed, the three-axis gyro system was proposed to stabilize the outer gimbal and the mechanism of this method was explained,then the control system was designed, the outputs of speed loop were compared between the three-axis gyro and the traditional two-axis gyro system, The results showed three-axis gyro system has higher stabilization accuracy than two-axis gyro system.
