Abstract

The laser guided missile has the advantages of strong anti-jamming ability and high accuracy of hit, which plays an important role in the past war. Compared with the active laser system, the semi-active laser system has the advantages of concealment, which makes the missile structure more simple and compact and the volume can be effectively reduced. The four quadrant detector is an important component of the seeker. Servo control system receives signal deviation to achieve target acquisition and tracking. The performance of the detector and control system of the semi-active laser servo platform directly determines the performance and strike capability of the whole missile system. This paper analyzes the algorithm and performance of the four quadrant detector in angle measurement, summarizes the types and action mechanism of laser interference, put forward the classification of active interference and passive interference. The characteristics of the semi-active laser detection system control system are analyzed, and the improved design is carried out on the basis of the traditional PID control system model. By introducing the disturbance compensation method and the method of adding the state observer based on speed and acceleration, the tracking speed and precision of the control system are improved. Finally, the effectiveness of the method is verified by simulation.
