摘要
随着人们生活水平的提高,用微电脑控制的模糊电饭煲已经逐渐走入人们的日常生活。本课题从实际工程出发,对基于模糊技术的电饭煲控制系统设计和应用进行了深入的研究。
电饭煲是一种典型的模糊对象,其特性随着其装载物的量和种类的不同而大大不同,而煮饭功能则是电饭煲的主要功能,同时也是衡量电饭煲控制系统优劣的关键功能,因此,本文在控制系统的软件设计方面重点研究了电饭煲的煮饭功能。准确地判断出米量是电饭煲能够实现最佳控制效果的重要保障。所以,本文着重讨论了在电饭煲煮饭过程中,如何利用模糊推理法进行米量的判断。首先通过大量的前期实验和测试,在具体了解米量的大小给系统的状态带来的影响的基础上,选用合适的输入变量用“试错法”设计了一种二维的模糊推理机,并详细讨论了其推理过程。
本文实际设计和实现了一种模糊电饭煲控制器。在系统硬件方面,讨论了模糊电饭煲控制系统的硬件结构。在软件方面,研究了模糊电饭煲控制系统的软件控制流程并给出其流程图,同时重点介绍了根据推理结果设计的米量判断程序的流程。
最后,本文针对模糊电饭煲设计和开发过程中参数调整的复杂性问题,提出了一种基于模糊电饭煲参数调整的专家系统。由于在参数调整的过程中同样是利用了煮饭专家的经验,而这些经验是有规律可循的,可以用思路清晰的程序语言表达。

ABSTRACT
With the living quality improved, the puter controlled electrical cookers are getting more and more popular. For practical uses, the design and application of a electrical cooker control system based on fuzzy control technology is studied, which aims at am or e effective control strategy.
This paper is mainly about the design of a kind of typical fuzzy object一electrical cooker, whose characteristics not only varies with the quantity of stuff in it but also varies with what kind of stuff it is.
As the result to estimate the amount of rice in round is crucial for control strategy. This paper discusses how to judge the amount of rice in the cooker if the electrical cooker is cooking rice. The differences generated by the amount of rice are found out by lots of tests. Two appropriate variables are selected as the input of the fuzzy reasoning machine to judge the amount of rice and the method "try and error" is applied. Details of the procedures of reasoning are displayed.
The controller of the system of the fuzzy controlled electrical cooker is set up. Both the hardware and the software are described in the paper. The main structure of the hardware is described in detail and for each parts, a sort of pop
