摘要
针对一类非线性系统提出了间接自适应模糊控制方法,该方法用模糊逻辑系统逼近未知函数,并设计误差补偿器来减少逼近误差对跟踪精度的影响。在设计等效控制时考虑其存在性,仿真证明该方法不但能使跟踪误差收敛到原点的小邻域内,而且通过适当调整设计参数,可使跟踪误差减小,收敛速度加快。仿真结果验证了此方法的有效性。
An indirect adaptive fuzzy control method for a class of nonlinear system is presented. In this .method, two fuzzy logic systems are used to approximate unknown functions, and an error compensator is designed to reduce the influence of approximation error on tracking accuracy. It is proved that this method can not only make the tracking error converge to the small neighborhood of the origin, but also reduce the tracking error and accelerate the convergence by adjusting the designed parameters. Simulation results show the effectiveness of this method.
