摘要
针对一类未知非线性系统 ,利用模糊逻辑系统、 H∞控制和高增益观测器 ,提出一种模糊直接鲁棒自适应输出反馈控制方法。证明了所设计的输出反馈控制方法不但能保证闭环控制系统稳定 ,而且可获得在状态反馈控制器下的性能。
By combining fuzzy logic systems and H ∞ control technique with high gain obsever, a fuzzy direct adaptive robust output feedback control scheme is developed for a class of unknown nonlinear systems. It is proved that the proposed control scheme can not only gurantee the stability of the closed loop, but also obtain the tracking performance achieved under state feedback control. The simulation result shows the effectiveness of the method.
