摘要
针对一类非线性系统的稳定控制器设计问题,根据广义模糊双曲正切模型的万能逼近性质,提出一种带有可调参数的广义模糊双曲正切模型的自适应控制器设计方法.该设计方法的优点是使得自适应律的个数不依赖于广义模糊双曲正切模型的线性基函数的输出形式,可以有效减少在线估计的参数数目,并且能够保证被控系统的状态一致终极有界.最后通过数值算例表明了所提出的设计方法的有效性.
The problem of controller design for a class of nonlinear systems stability is discussed. A design method of generalized fuzzy hyperbolic model adaptive control with adjustable parameters is proposed according to universal approximation properties. The advantage of the design method is that the number of adaptive laws do not depend on the linear basis function of the output of the generalized fuzzy hyperbolic model, which can reduce the number of on-line parameters, and also guarantee the states of systems uniformly ultimately bound（UUB）. Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
