摘　　要：提出了一种基于遗传算法优化RBF网络滑模变结构控制的空空导弹三维导引律,解决了一般滑模变结构控制中存在的抖振问题,提高了导引系统的鲁棒性。该导引律在目标机动的情况下,亦能实现很好的导引效果。仿真结果表明,该导引律与比例导引相比有较大的性能改善。In this paper, based on genetic algorithm optimal RBF net, a 3-D intelligent sliding mode guidance law for air to air missiles is proposed. The method has not only solved the problem of chattering existed in common sliding mode control, but also improved the robust capability of the guidance system. In the case of target making some movement, the guidance law also achieves a perfect guidance result. The numerical simulation results show that the 3-D intelligent sliding mode guidance law has much better performance than that of proportional navigation.
