零控脱靶量有限时间收敛制导律
Finite time convergent zero-effort miss guidance law
摘要
Abstract
A finite time convergent zero-effort miss guidance law considering the dynamics of the missile autopilot is proposed for the problems of intercepting high speed and maneuvering targets.The three-dimensional relative geometric relation between the missile and target is decoupled. A new three-dimensional zero-effort miss guidance model incorporating the dynamics of the missile autopilot is derived.Based on the adaptive sliding mode control theory and the finite time stability theory,the zero-effort miss in pitch plane and yaw plane is chosen as the sliding mode surfaces,and then the three-dimensional adaptive sliding mode guidance with finite time convergent zero-effort miss is proposed.The guidance law’ s stability and finite time convergence ability are analyzed and proved.Simulation results show that the proposed guidance law can achieve the finite time convergence of the zero-effort miss,and has better guidance precision compared with the proportional guidance law.关键词
