Three-Dimensional Guidance Law with Attack Angle Constraint Considering the Dynamic Characteristics of the Control System

摘要

Aiming at the requirement of attack angle control of guidance weapon and the adverse effect of dynamic characteristics of control system on the guidance effect, a guidance law with terminal attack angle constraint considering the dynamic characteristics of the control system is proposed. Based on sliding-mode variable structure control theory, a three-dimensional guidance law is designed by using backstepping design method, which realizes the compensation of the delay characteristic of the control system, and the guidance law convergence is proved by using Lyapunov stability theory. Finally, the effectiveness of the guidance law is verified by comparing with the adaptive sliding mode guidance law.
