一种新的有限时间收敛的末制导律设计
A New Terminal Guidance Law Design with Finite Time Convergence
摘要
Abstract
For the case of a three-dimensional interception, a new nonlinear terminal guidance law with finite time convergence is proposed. Firstly,the basic design rules are given according to the mathematic model of three-dimensional relationship between missile and target. Secondly,a new integral sliding mode is present to avoid the singular problem of traditional terminal sliding mode. A robust terminal guidance law is designed,zeroing the rate of line-of-sight angle and finite time convergence stability of guidance system are strictly proven by Lyapunov stability theory. Finally an illustrative example is given to show that better precision and finite time convergence stability are obtained under the new guidance law for intercepting the target with maneuver than proportional navigation law.关键词
