Guidance Law for Interception of Jumping Maneuvering Target
摘要
Abstract
A nonlinear guidance law is proposed to confront the challenge of offensive near-space ve-hicles.Firstly, 3-D relative motion equations of missile and target are built in sight coordinate system. The gradient of target jump range is introduced to estimate its maneuverable capability.An adaptive slid-ing mode reaching law varying with the gradient of target jump range and the distance between missile and target is designed.3-D guidance law in sight coordinate system is got based on sliding mode control theo-ry.Secondly, the allocation strategy of reaction-jet/aerodynamic multi-control is designed and trajectory-control lateral-jets control technology is used in the terminal phase.Simulation results show that intercep-tor using this guidance law and control strategy can hit hypersonic and high maneuvering target accurately. Meanwhile the flight ballistics is smoother and required overload is lesser as well as energy consumption.关键词
