Abstract
In order to improve the tracking performance of airborne electro-optical tracking and pointing platform, fuzzy control was used together with PID control.The adaptability of the Fuzzy PID controller was improved by changing the fuzzy input and output variables, thus can enhance control performance of the airborne electro-optical tracking and pointing platform.Simulation results show that the method has preferable robustness, and can decrease overshoot, shorten response time and improve control accuracy.
