摘要
提出了一种基于自适应模糊滑模控制的空空导弹三维制导律,解决了一般滑模控制中存在的抖振问题。该制导律在非线性系统的精确模型未知的情况下,通过模糊系统对非线性模型进行逼近,并根据Lyapunov方法设计了参数自适应律。仿真结果表明,该制导律与比例制导相比有较大的性能改善。
In this paper, a 3-D Adaptive Fuzzy Sliding Mode Guidance law (AFSMG) for air to air missiles is proposed. The method has solved the problem of chattering existed in common sliding mode control. The air to air missile model is approximated by fuzzy system in case that the precise nonlinear model is not obtained. Lyapunov method is used for designing the adaptive parameters of fuzzy system. The numerical simulation resuits showed that compared with proportional navigation(PPNG), AFSMG has much better performance.
