摘要 为了保证布尔模糊系统逼近定义在紧集上任意实值连续函数的逼近精度,给出一个估计布尔模糊系统的输入变量与输出变量各自需要构造的模糊集个数的公式,讨论如何设计布尔模糊系统,以便实现逼近任给的实值连续函数到需要的逼近精度.最后通过一个例子展示了如何设计布尔模糊系统来逼近所给的连续函数的具体方法. A formula is given to compute the minimal upper bounds on the number of fuzzy sets and achieve prespecified approximation accuracy for any multivariate continuous function. One example is provided to show the way in which Boolean fuzzy systems are designed to approximate given functions with a given required approximation accuracy.
