基于反演思想的导弹自适应模糊控制

Adaptive Fuzzy Control of Missile Based on the Idea of Backstepping

首先对导弹过载模型形式进行了合理的变化,转化为严格反馈形式。基于反演设计的思想分别对对象的各个子系统进行了自适应模糊控制器的设计,利用李雅普诺夫稳定性理论进行了控制器稳定性分析并得到了模糊参数的自适应调节律。最后仿真结果验证了模糊控制器的有效性。

Firstly,some plausible changes arc made,such that the nonlinear pitch acceleration model of missile ean be changed into strictly feedback form.Based on the backstepping idea,adaptive fuzzy controller is designed for each subsystem,and Lyapunov Stability Theorem is used to analyse the global stability of the system,and the update laws of the parameters of the fuzzy systems arc obtained.Finally,the simulation results have shown the merits of the proposed scheme.
