| 中文摘要 |
| 本文针对一类带有未知齐次函数的非线性系统, 首先基于伸缩器和饱和器的概念, 将T-S型模糊逻辑系统的输入–输出进行改造而形成扩展模糊逻辑系统, 然后利用扩展模糊逻辑系统给出一种带有可调伸缩因子参数的模糊自适应控制器的设计方法. 由于该方法不依赖模糊规则数目, 因而不仅能有效减少在线估计的参数数目, 而且能够保证被控系统的状态一致终极有界. 最后所给数值仿真算例说明了该设计方法的有效性. |
| 英文摘要 |
| A class of nonlinear systems with uncertain homogeneous functions is discussed. At first, the inputs and outputs of the T-S fuzzy logic system are constructed to form the extended fuzzy logic system(EFLS) based on the definitions of scalers and saturators; and then a design method of fuzzy adaptive control with adjustable scaler parameters is proposed by using the extended fuzzy logic systems. Because the method does not depend on the number of the rule base, the design method not only reduces the number of on-line parameters but also guarantees the uniformly ultimately bound(UUB) of the system. Finally, the simulation shows the validity of the proposed method. |
