Abstract :
To guarantee the transient performance of interception system, L1 adaptive control is proposed to design the integrated control law for the guidance and control of interceptor. The nonlinear model of the integrated guidance and control (IGC) in pitch channel is built. Based on state feedback, the linear reference system that affects the transient performance is chosen to design the L1 adaptive controller. This method guarantees robustness and transient performance in the presence of uncertainties. And thus it improves the anti-interference and timeliness of interception. Simulations are done with different kinds of uncertainties and different controller parameters. The results demonstrate the robustness and guaranteed transient performance of the proposed controller.
