针对一类高阶非线性系统提出了一种稳定的自适应模糊变结构控制方案 ,它既可以利用模糊描述信息 ,又可以利用变结构控制 .并提出了参数适应律 ,保证有关参数的有界性 ,并用李雅普诺夫方法保证了系统的全局稳定性 .该文的控制算法有良好的控制性能 For a class of higher order nonlinear systems, a stable adaptive fuzzy variable structure control scheme is proposed, which can not only make use of fuzzy descriptor information but also make use of variable structure control. The parameter adaptation law is proposed to ensure that the relevant parameters are bounded And using Lyapunov method to ensure the global stability of the system.The control algorithm in this paper has good control performance
