中文摘要 |
模糊系统的设计可看成是一类函数逼近问题, 从而可以利用数值逼近的方法来设计模糊系统. 本文将B样条函数引入到模糊系统的设计中, 构造了两类多输入单输出的B样条模糊系统, 并证明了它们均能逼近函数及其导函数. 仿真结果表明, 将两类B样条模糊系统应用到模糊系统建模和模糊控制器设计是可行的, 且在大多数情形下, 第1类B样条模糊系统的性能优于本文提到的其他模糊系统. |
英文摘要 |
The design of a fuzzy system can be considered as a function approximation problem. Thus, fuzzy systems can be designed by using numerical approximation methods. In this paper, the B-spline function is introduced to design fuzzy systems, and two classes of multiple-input-single-output (MISO) B-spline fuzzy systems (B-FSs) are constructed, both of which can approximate functions and their derivatives simultaneously. Simulation results show that it is feasible to use B-FSs for fuzzy system modeling and fuzzy controller design. In most cases, the first classes of B-FSs outperform the other fuzzy systems mentioned in this paper. |
