The control system for correction projectile is a strongly nonlinear and time-varying complicated system. Conventional PID controller has been widely used in the control system of ammunition. But it cannot achieve highly control effect because of the complexity and uncertainty of system model. With fuzzy control and fractional order control theory, this paper puts forward a fuzzy fractional order controller through taking correction projectile as controlled object. On one hand, self-adaptive

Simulation results show that the the fuzzy fractional order PI λ D μ controller demonstrates the better time domain response characteristics compared with the fractional order PI λ D μ controller and the conventional PID controller, and can be used to improve the robustness of the system in the correction projectile system control.
