Head Pursuit Adaptive Nonlinear Guidance Law

摘要

An adaptive nonlinear guidance law is presented for high-speed targets in a novel head pursuit engagement.In this paper,the guidance law is designed through an objective geometric which makes the guidance law to be much more reliable than the perfect head pursuit.What's more,the interceptor and target maneuver dynamics were taken into consideration.And adaptive sliding mode theory is used to devise head pursuit guidance law.By using this approach,the target dynamics can be considered without knowing its acceleration boundary.The robustness of the presented guidance law is derived theoretically in this paper.At last,numerical simulation results verify the performance of the presented adaptive nonlinear guidance law in several typical situations.
