摘要
对高阶非线性系统设计了模糊直接自适应控制器。用高木—关野型模糊系统作为控制器 ,用鲁棒控制项对未知的逼近误差进行补偿以减小逼近误差对跟踪精度的影响。所给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或其小邻域内 。
A direct adaptive controller is designed for higher order nonlinear system In this system, T S fuzzy model is used as a controller, and robust control term is used to compensate for approximation errors The method not only guarantees the stability of the close loop system, but also reduces the tracking errors It also eliminates the influence from external disturbances
