【Abstract】 A new method based on the self-adjusting fuzzy-PID control is presented,which is suitable for ATP(acquisition,tracking,pointing)servo system for optical space communication.The advantages of fuzzy control and traditional PID control were combined in this method.The design method of fuzzy-PID controller is discussed.The design and simulation of the system were implemented by using the fuzzy control tool box in MATLAB.The comparison of the obtained result with that of the conventional PID controller was carried out.The simulation results show that the system is much better than the conventional PID controller,and the LOS(line-of-sight)stability of ATP system is improved.更多还原
