Based On Fuzzy Pid Cruise Missile Autopilot Design Method

For missile parameters changing abruptly in flight process, fuzzy control theory is selected to design the autopilot. Aiming at a guided missile, the controller is introduced on the basis of the classical control system. An autopilot for a kind of missile is designed by the theory of Fuzzy-PID control. At first, the model of aerodynamics missile is given in this dissertation. Secondly, the principle of fuzzy control and the structure and the design of Fuzzy-PID control are introduced. Based on this, Fuzzy-PID controller applied to aerodynamics missile system is designed with simulation by Matlab, analysis in detail to the control effect is processed. The research shows: Fuzzy-PID controller is independent of the system model, and it is prior to general PID in response speed and stable precision and restraint ability against the interference. It is proved that the method is reasonable and feasible.
