摘要
针对未来导弹拦截高速大机动目标高精度制导的需要,为使导弹制导系统具有良好的鲁棒性能和精确性;提出了一种全局快速Terminal滑模的鲁棒末制导律设计方法;全局快速Terminal滑模鲁棒末制导律通过引入非线性项,代替传统线性变结构滑动模态的设计,可使目标视线角速度在有限时间内收敛到零,可以满足导弹对目标零脱靶量的要求;通过对不同的机动目标进行仿真,结果表明该方法具有较强的鲁棒性和抗干扰能力,对各类机动目标均有较高的制导精度。
In order to intercept high maneuvering targets, a new robust fast terminal guidance law is proposed. Based on the terminal variable structure control theory, the tracking error on the sliding surface can converge to zero in a finite time. Through the tests by using different maneuvering targets with unknown target accuracy, the simulation results show that this law has strong robustness and high guidance precision while intercepting all kinds of maneuvering targets.
