In this article a L 1 adaptive state feedback controller is presented for the three-dimensional integrated guidance and control of interceptor. The model of three-dimensional integrated guidance and control is first built by using engagement kinematics and interceptor dynamics. The objective is to control the fin deflection angles to make the line-of-sight rates converge to zero. The L 1 adaptive control is then applied to design the three-dimensional integrated guidance and control controller. The L 1 adaptive controller guarantees uniformly asymptotic and bound transient tracking for the system inputs and outputs, which are important for interceptions with strong robustness and high timeliness. The design issues of L 1 adaptive controller are also discussed. In the interception simulation, the L 1 adaptive state feedback controller demonstrates the robustness to different kinds of uncertainties, while guaranteeing the transient performance of dynamic interception process.
