摘要 针对一类带有未知外部扰动的不确定非线性系统,建立自适应模糊滑模控制器。基于Lyapunov稳定性理论,设计系统可调参数的自适应规则,控制器的设计过程中无需知道系统的具体模型及未知非线性函数的先验知识。数值仿真的结果也验证了该方法的有效性。 The tracking problem for a class of unknown nonlinearities systems with unknown disturbance is considered. By utilizing Lyapunov stability theory, the adaptive fuzzy sliding mode controller is established. And the upper knowledge of the model uncertainties and the model of the nonlinear systems are not required to be known. The effectiveness of the proposed fuzzy adaptive controller is illustrated throughout the simulation results.
