The underwater interceptor’s target have the characteristics of small size, fast speed and strong maneuverability, which requires the underwater interceptor guidance system to have fast and stable response capability. Aiming at the design requirement, this paper proposes a global sliding mode controller of integrated guidance and control(IGC). The integrated guidance and control mathematical model of the underwater interceptor’s lateral channel is established, and the global sliding mode control based on the adaptive regulation law is designed aiming to the problem of uncertainty about the emergence of an integrated system for the target maneuver. The asymptotic stability is proved by applying the Lyapunov theorem. Then the high-gain continuing method is adopted to restrain the buffeting for the IGC system. The proposed controller compensates the uncertain information and improves the robustness and fastness of the system. The simulation results show the effectiveness.
