Abstract:the missile in flight with a non-linear,coupled and time-varying ,in addition,the flight parameters have rapid changed,the traditional PID control can not meet the requirements of dynamic control.Aiming at this problems,in this paper put forward a kind of effective method to control missile attitude, improve the controllability of the missile control system.As missile pitch channel for an example,Based on the PID fuzzy control theory,designed a parallel fuzzy PID controller,and given the relationship about controller and the coefficients KP, KI, KD of the conventional PID controller .The simulation results show that the scheme has good stability, effectively reducing the amount of regulation time and the system overshoot.
