1、 毕业论文传感器在模糊控制洗衣机中的应用研究第 I 页传感器在模糊控制洗衣机中的应用研究摘 要模糊控制是首先对控制对象按照人们的经验总结出模糊规则,然后由单片机对这些信息按照模糊规则做出决策来完成自动控制。首先，本文将概述模糊控制的基本原理和特点，并研究模糊控制在洗衣机中的应用方面。例如，在洗涤衣物过程中，衣物的多少，面料的软硬等都是模糊量，所以首先做大量的实验，总结出人为的洗涤方式，从而形成模糊控制规则。其次，本文将根据模糊控制原理对洗衣机的水位控制进行具体的研究，具体主要是模糊传感器的应用，即利用模糊传感器实现对洗衣机水位的测量，并把得到的数据经单片机 A/D 转换后，输出结果。最后，通过
2、 MATLAB 仿真器在实际设计中的应用，模拟研究是模糊洗衣机加水和排水的模糊控制。通过建立模糊推理系统，完成模拟量的函数关系及函数图像，验证得出模糊传感器较以往的传感器更加智能化，便捷化，为人们的生活节约了许多不必要的麻烦。关键词：模糊控制，隶属度函数，模糊推理系统，模糊传感器第 II 页The Sensors applied research in the fuzzy control of washing machines Author：Zhang danyangTutor：He jintianAbstractAccording to peoples experience, the fuz
3、zy control summarizes the fuzzy rule to the controlled member at first, and then according to the fuzzy rule, it makes the decision-making to complete the automatic control by the monolithic integrated circuit to this information.First, this article will outline the fuzzy control the basic principle
4、 and the characteristic, and elaborates the fuzzy control in washers application aspect. For example, in the clothing washing process, the fuzzy quantity contains how many clothings, the lining soft or hard and so on, therefore first does the massive experiments, and summarizes the artificial wash w
5、ay, thus forms the fuzzy control rule. Next, according to the fuzzy control this article will act principle to conduct the concrete research to washers water monitor, which is mainly the fuzzy sensors application specifically, namely the use fuzzy sensor realizes to the washer water level survey, an
6、d the data which obtains after the monolithic integrated circuit A/D transformation will be put out.Finally, the simulator study is the fuzzy washer watering and the draining water fuzzy control through the MATLAB simulators in actual design application. Through the establishment fuzzy reasoning sys
7、tem, the simulation quantity completes the functional relations and the function image, and the confirmation obtains the fuzzy sensor former sensor more intellectualized, convenient, saved many nonessential troubles for peoples life.Key words: Fuzzy control, Membership function, fuzzy inference syst
