摘要：【中文】具有规定性能的拦截机动目标自适应滑模控制方法，涉及制导技术领域，针对现有技术在具有视线角约束的制导律设计中，常规的制导律只能限制制导终端视线角收敛到给定的角度，进而使得制导系统的视线角在整个制导过程中不能够满足收敛速度要求和稳态误差要求的问题，本发明保证了制导系统的视线角能按规定的性能约束函数进行收敛，在导弹拦截隐身目标或者多导弹协同制导等场景中，制导系统的视线角应满足特定的约束，本发明可以利用设计的性能约束函数对制导系统的视线角收敛时间，稳态误差和超调量进行限制。可以更好的改善制导系统的性能，并且实施方式简单，能容易的应用到其他非线性系统的控制问题中。 【EN】The invention discloses an interception maneuvering target self-adaptive sliding mode control method with a specified performance, relates to the technical field of guidance, and aims to solve the problem that in the prior art, in guidance law design with line-of-sight angle constraint, a conventional guidance law can only limit a guidance terminal line-of-sight angle to be converged to a given angle, so that the line-of-sight angle of a guidance system cannot meet the requirements of convergence speed and steady-state error in the whole guidance process. The performance of the guidance system can be better improved, the implementation mode is simple, and the method can be easily applied to the control problem of other nonlinear systems.
