针对一类非仿射的不确定非线性系统,利用H^∞控制技术和模糊系统,提出一种基于观测器的混合的直接自适应模糊控制方法,该方法不需要系统的状态变量完全可测,同时取消了最优逼近误差平方可积的假设条件,而且跟踪误差渐近收敛到零。仿真结果表明所提设计方法的有效性。
In this paper, the observer-based direct adaptiv technique and fuzzy systems for a class of nonaffine u approaches do not need to be available for the state variabl of the approximation error is avoided but also get a good tracking perfo stability theorem, the closed-loop adaptive fuzzy control system is proved ultimately bounded, with the observing error of the tracking error conve The simulation results are performed to demonstrate the effectiveness of rmance. Based on Lyapunov to be semi-globally uniformly rging to zero asymptotically. the proposed method.
