【Abstract】 In order to improve the tracking area and application field of the Acquisition Tracking Pointing (ATP) system, A real time changing focus tracking control system is developed based on the principle of optics and modern control theory. It can change focus of tracking TV according to tracking object size, distance and shape, so it changes the tracking inspect field to capture any complicated objects. With expert control theory, a robust PID controller is designed to tolerate parameters changing of the system. Simulation and experiment results indicate that tracking system not only can capture some complicated object fast , but also can meet the needed performance of dynamic and steady-state of the system. It completes the function of real time changing focus continuously and control successfully.更多还原
