一类不确定非线性系统的自适应模糊控制

对一类不确定非线性系统提出自适应模糊控制方法。此方法用模糊逻辑系统设计自适应模糊监督控制器和自适应模糊控制器，且设计补偿器对逼近误差进行补偿，以此来减少逼近误差对跟踪精度的影响，同时对自适应模糊监督控制器和自适应模糊控制器中的未知参数设计了自适应学习律。证明了该方法不但能保证闭环系统稳定，而且可使跟踪误差收敛到原点的邻域内。仿真结果验证了此方法的有效性。

Adaptive fuzzy control for a class of uncertain nonlinear systems

An adaptive fuzzy control method for a class of uncertain nonlinear systems is presented.In this method,the adaptive fuzzy supervisory controller and the adaptive fuzzy controller are designed by a fuzzy logic system,and an error compensator is designed to reduce the influence of the approximation error on tracking accuracy,meanwhile,the unknown parameters in the adaptive fuzzy supervisory controller and the adaptive fuzzy controller are adjusted adaptively.It is proved that this method can not only guarant...
