Observer-based adaptive fuzzy control for a class of nonlinear systems
基于观测器的一类非线性系统的自适应模糊控制

An observer-based robust adaptive controller for a class of nonlinear systems with uncertainties and external bounded disturbances is presented.It is assumed that only the system output variable can be measured,the state variables are estimated via a fuzzy observer that can guarantee the uniformly ultimate bounds of the observer errors.The adaptive controller with a fuzzy observer is designed to control a class of nonlinear systems with uncertainties and external bounded disturbances,and the adaptive controller can guarantee the uniformly ultimate bounds of the tracking errors.Simulation results demonstrate the effectiveness of the proposed method in order to achieve the desired performance.
