Abstract： Actuator is an important equipment of missile control system，and its performance can affect the battle capability of missile. Aiming that the missile's nonlinear characteristic in different flying environment，the traditional PID controller can't afford the needed performance，an adaptive control method based on hyper stability was proposed to solve the problem. According to electronic actuator's principle，its state model was constructed and adaptive controller was designed. Analysis of actuator system was completed using Matlab/Simulink. The simulation results indicate that the adaptive controller can solve the problem of bad effect of traditional PID control method and can conquer the difficulty caused by the actuator's parameter fierce change，and actuator is able to follow the command quickly and stably.
