• 中文摘要： 本文提出收縮幅寬隸屬度函數,作為設計模糊邏輯控制器的依據。使用者只需設定每一個口語化變數之口語化值之個數及其收縮因子,便可以得到一組不等距之隸屬度函數,稱為收縮幅寬隸屬度函數。本文將說明此種隸屬度函數的設定方式及其優點,同時將其應用於模糊邏輯控制器的設計中,並針對於一般常用之二輸入-單輸出型式之模糊邏輯控制器進行研導,以求得簡易之輸入-輸出關係式,藉此簡化控制器之計算流程。
• 英文摘要： A new means for designating membership functions in a fuzzy logic controller is presented in this article. This method constructs a set of membership functions systematically by using only two parameters: number of fuzzy subsets and shrinking factors. The membership functions generated by this method, called Shrinking-Span Membership Functions (SSMFs), have different spans in the universe of discourse and, therefore, are more rational and more practical from the human experts' point of view. The fuzzy logic controller equips with such membership functions (SSMFs-FLC) can be implemented with little difficulties. And the satisfactory performance of the controller can be acquired without laborious optimization calculation of the tuning parameters. Since it lessens the load of computation in realizing a fuzzy logic controller, this new approach greatly narrows the gap between a theoretical fuzzy logic controller and a practical one, and thus help the fuzzy logic controller more down-to-earth.
