摘要
对一类非线性不确定连续系统,提出了一种新的自适应控制方法。此方法用T-S模糊系统对未知函数进行逼近,引入H^∞控制减弱外部干扰及逼近误差对输出跟踪误差的影响,证明了该方法可保证闭环系统稳定。仿真结果验证了此算法的有效性。
A new adaptive fuzzy control method is presented for a class of continuous uncertainty systems. In this method, T - S fuzzy logic systems are employed to approximate unknown functions in the sytems, H∞ control is used to attenuate the effect on the tracking error caused by fuzzy logic approximation errors and external disturbance. It is proved that this control algorithm can guarantee the stability of the closed - loop system. The simulation example is given finally to illustrate the performance of the proposed method.
