一种应用于自主车辆的新型自适应模糊控制器

摘要

Adqptive control for a class of nonlinear systems is discussed in thes paper ,We use fuzzy systems to approximate the ideal optimal controller by aduusting the parameters of fuzzy systems,In order to tune these parameters,linear relationship between aproximation error and parameters in established firse. Then we design the adaptive laws of these parameters based on Lysapunov synthesis approach.The advantage of our method is that we can tune not only the parameters of the consequences of fuzzy rules,but also the parameters of the membership functions.As a result ,a stable and nore flexible controller is achieved.Hye performance of the adaptive scheme is demonstrated through the longitudinal vehicle control.
