Integrated guidance and control (IGC) design is a new trend in missile technology. In this article a L1 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 L1 adaptive control is then applied to design the three-dimensional integrated guidance and control controller. The L1 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 L1 adaptive controller are also discussed. In the interception simulation, the L1 adaptive state feedback controller demonstrates the robustness to different kinds of uncertainties, while guaranteeing the transient performance of dynamic interception process.
