• 中文摘要： 本文首先檢討Ying、Siler和Buckley(1990)所提出最簡易模糊控制器之伺服控制性能,發現其僅具與傳統比例積分控制器相當之性能。本文隨即提出具雙控制律之修正最簡易模糊控制器,此控制器在誤差大時相當於一個非線性比例微分控制器; 在誤差小時則相當於一個非線性比例積分控制器。模擬結果說明此一修正可以提供優於傳統比例積分微分控制器之效果。
• 英文摘要： The achievable performance of Ying, Siler, and Buckley's (1990) simplest possible fuzzy controller has been discussed in this article and found to not necessarily be better than that of the conventional proportional integral(PI) controller, as contrary to the claims of the above authors. The simplest fuzzy controller of Ying et al. was modified in this study to create a novel simplest fuzzy controller incorporating dual control laws. The resulting dual-laws fuzzy controller was proven to be analytically equivalent to either a nonlinear proportional-derivative (PD) or a nonlinear PI controller, depending on the degree to which the controlled variable departed from the reference point. Several simulated examples have been supplied for demonstrating that such a dual-laws fuzzy controller could provide a superior performance in handling servo problems than could the conventional PI controller or the simplest fuzzy controller of Ying et al..
