固定时间收敛的预设性能攻击时间控制制导方法OA
Performance prescribed impact-time-control guidance law with fixed time convergence
针对飞行器指定攻击时间命中机动目标问题,提出一种自适应预设性能攻击时间控制制导方法.考虑到误差收敛时间对攻击时间控制制导律命中时间精度的影响,给出一种具备固定时间收敛特性的性能包络函数,提出可固定时间收敛的预设性能制导律,并分析性能函数参数选取与初始加速度变化之间的关系.通过对性能函数参数的设置,可结合飞行器自身机动能力实现对攻击时间误差瞬态性能和稳态性能的调节,并使得攻击时间误差在攻击时间指令前收敛至性能函数包络范围内.仿真结果验证了所提出制导方法的有效性和正确性.
This paper investigates the problem of impact time control guidance of flight vehicle intercepting maneu-vering target,an adaptive impact time control guidance law is proposed with prescribed performance.Considering the influence of the convergence time on the hitting time accuracy of the impact time control guidance law,the paper presents a performance envelope function with fixed time convergence.A prescribed performance guidance law is proposed with fixed-time convergence.The relationship between the selection of the performance function parameters and the variation of initial acceleration is analyzed.By setting the parameters of the performance function,the transient and steady-state performance of the impact time error can be adjusted in combination with the maneuvering capability of the flight vehicle,and the impact time error can converge into the performance function envelope prior to the impact time command.The simulation results are presented to validate the effectiveness and correctness of the proposed guidance method.
