| 摘 要： | 针对一类非线性系统把模糊控制、模糊逻辑逼近及模糊滑模控制相结合，提出一种综合自适应模糊控制方法．基于李亚普诺夫函数系统参数的自适应律，不需要最小逼近说差平方可积条件，而且利用模糊滑模控制补偿模糊系统的逼近最差及外部干扰对输出跟踪误差的影响，理论证明了闭环系统稳定，跟踪误差收敛到零或零的一个小邻城内．仿真表明了算法的有效性。

| Abstract: | The method of compositive fuzzy adaptive control systems was proposed for a class of nonlinear system based on combination of fuzzy control, fuzy logic system approach and sliding mode control, based on parameter adaptive variability in fuzzy system obtained by Lyapunov measure. Method doesn't need the square integrable condition of approximation error, and using fuzzy sliding control to compensate approximaiton error of fuzzy system and output tracking error affect of external disturbance. And then the stability of closed system was analyzed, tracking error of system gradually converge to zero or a neighborhood of zero. Simulation showes the validity of arithmetic. |
