Research on Backstepping Control of Simplified Uncertain Supersonic Missile Model

A new kind of adaptive backstepping method is proposed for simplified missile model of pitch channel with time-varying and uncertain parameters. Backstepping control is an effective method for coping with system uncertainties. Adaptive method is integrated with backstepping method and a Lyapunov function is constructed to guarantee the whole system is stable. Through the theoretical analysis and numerical simulation, comparison between PID control and backstepping control shows that the backstepping control for the uncertain missile system has a better control effect. And compared with the PID control method, backstepping control has better robustness. Keyword: Uncertain supersonic missile, Backstepping control, PID control, Second order system
