H_∞ optimal output tracking control for dual-controlled missile with tails and reaction jets based on dynamic inverse theory

A control scheme is proposed for dual-controlled missile with tails and reaction jets based on the dynamic inverse theory and H_∞ optimal output tracking control. In the scheme, the nonlinear factor of dual-controlled missile is considered, the dynamic inverse loop is used as inner loop of control system to counteract the nonlinear factor, and the robust controller is used as outer loop under the consideration of uncertainty and disturbance. The robust controllers are designed with H_∞ control and optimal output tracking control to restrain the disturbance and preference uncertainty effectively and improve the tracking performance of control system. Simulation results show that the control system possesses better robustness and improves the tracking performance of system.
