摘　　要：针对攻击角约束的机动目标拦截问题,提出了一种任意时间制导律。该制导律的设计采用了任意时间稳定性理论和分段滑模方法,解决了有限时间和固定时间制导律收敛时间难求的问题,实现了视线角误差收敛时间的任意设定。此外,还利用相关稳定性理论,对所设计的制导律进行分析与证明。通过数值仿真验证了任意时间制导律的有效性,并与有限时间和固定时间制导律的仿真结果进行了比较。An arbitrary time guidance law is proposed for the interception of maneuvering targets with impact angle constraints.The design of the guidance law adopts the arbitrary time stability theory and the piece-wise sliding mode method which solves the problem that it is difficult to obtain the convergence time of the finite-time and fixed-time guidance laws and realizes the arbitrary setting of the convergence time of the line-of-sight angle.The designed guidance law is analyzed and proved by using the relevant stability theory.The effectiveness of the arbitrary time guidance law is verified by numerical simulation and the simulation results are compared with those of the finite-time and fixed-time guidance laws.
