一种Terminal滑模制导规律研究
A Guidance Law Based on Terminal Sliding Mode
摘要
Abstract
To intercept high-speed big-maneuvering target,the nonlinear dynamic model of interceptor-target in longitudinal plane was built.Based on the terminal variable-structure control theory in which the tracking error on the sliding mode surface can converge to zero in finite time,the terminal sliding-mode guidance law in longitudinal plane was designed,and the asymptotic stability of guidance system was strictly proven by Lyapunov stability theory.The method of continuing the relay characteristics was introduced to guidance law design,and the law was improved to realize the quasi-sliding mode dynamic control.Simulation results show that the guidance law can make the LOS(line of sight) angular rate converge to zero in finite time.The guidance law can meet the requirements such as kinetic kill vehicle with low overload,limited fuel and small miss-amount,and it offers references for engineering application.关键词
