Design and Realization of Control System for Electro-Optical Searching and Tracking System Based on Compound Control

High precision control system is one of the key factors to ensure the stable target tracking for electro-optical searching and tracking system.In order to improve the response speed and control precision of the electro-optical searching and tracking system,a compound control strategy is proposed based on position feedforward and expert PID controller after the introduction of the overall system function and the control system modeling.The practical application shows that the control system can realize the high-precision and stable tracking of the target and has a good robustness.The control system meets the design requirements very well.
