中文摘要：
探讨了拦截机动目标情况下的攻击角度约束导引律设计问题。首先假设自动驾驶仪为理想环节,推导了一种滑模导引律,证明了该导引律的有限时间收敛特性。然后通过非线性反步设计法把上述导引律推广到考虑导弹自动驾驶仪动态延迟的情形上,仿真结果表明,导弹自动驾驶仪为实际跟踪环节,目标做大机动逃逸时该制导方法仍具有良好的制导性能。
英文摘要：
A terminal guidance law with angle of attack constraint is designed to intercept maneuvering targets in this paper.Firstly,the sliding mode guidance law is derived from the premise of autopilot with ideal dynamic delay.The convergence property within finite time is demonstrated.Furthermore,the guidance law is extended to the case of dynamic delay of autopilot by using the nonlinear backstepping method.The simulation results demonstrate that the proposed guidance law provides better performance when the autopilot has actual delay and target makes escape maneuver.
