摘要


以往,我們為了一個受控系統(Plant)能夠正常運作,讓使用者能夠方 便控制,通常我們必須再耗費時間開發出能夠控制此受控系統的控制器。 例如:電視、空調器都必須要有一個遙控器來做控制。但是,開發此控制 器可能極為複雜。我們都知道"人"是最好的控制器,因為人有豐富的知識 和經驗。一個以微處理機為基體的模糊控制系統,使我們在開發此控制器 的過程變得容易,也控制得更好。在模糊邏輯控制強調的是"單按鍵"控制 ,其完全根據知識庫及模糊規則做控制,使控制過程更具人性化。雖然使 用微處理機做為控制器已經非常普遍,但是一般微處理機在控制器中只有 運算功能,嵌入了模糊邏輯之後,微處理機不再只有計算功能,更增加推 理能力,提昇了微處理機在控制器中的功能。我們用電梯群的管理控制, 來證驗微處理機嵌入式模糊邏輯系統。一個電梯群控制,主要目的是使顧 客在搭乘電梯時等待時間最短、電梯達成最有效率的使用,少做虛工,是 一個最合適電梯的選擇系統,更廣泛的說是從許多解之中找尋一最佳解, 可以應用到許多實際生活例子中。

Some problems are too complex, ill-defined or ambiguous to describe completely by precise definitions. These problems are humanistic in nature, they represent problem domains that the human mind is more capable of handling. Therefore, to employ traditional approaches of scientific thinking by formulation the problems of humanistic systems and analyzing them in quantitative terms is unfeasible. We are no longer dealing with true or false, but with the range between true and false. From such realizations, fuzzy sets theories emerged. Fuzzy logic is not only designed in software on a conventional controller but also implemented a new chip that is specifically adapted to do fuzzy logic calculations. It is easy to design fuzzy logic in software, but it is hard to implement a fuzzy chip. Today, microprocessors can be embedded into application system popularly.The functions of these microprocessors embedded system are concentrated on computation and processing but not intelligent. These processors can be improved their capability by adding the fuzzy logic. The control application system can be worked smarter, like human thinking, with rule reasoning. We will implement the microprocessor embedded system in a management system of elevator group.
