I performed simulation studies, taking the electric heating boiler as the research object, through the analysis and Research on fuzzy control method, using MATLAB in the Simulink and the Fuzzy toolbox simulation analysis. Through the fuzzy control method is applied in the boiler temperature control system,we can overcome the serious lag phenomenonthe in the temperature control system, and can improve the stability of the system. The following is the chapter division: The first chapter introduces the research background and significance, the development status of the domestic and foreign boiler temperature control system, the significance of this topic and the main work of this paper The second chapter introduces the development history, the fuzzy control theory and the basic idea and characteristics, the fuzzy controller and fuzzy control algorithm. The third chapter introduces the analysis of controlled object and its control method. The fourth chapter introduces the simulation design of temperature control system for electric boiler characteristics, the fuzzy controller and the temperature control system. The fifth chapter is a brief summary of the whole thesis. Keywords: temperature-control system; electric boiler; fuzzy control; MATLAB 1 绪论 1.1 课题的提出和意义 温度是人类在生产过程和科学实验中非常普遍而又非常重要的参数。在工业许多生产过程中，为了提高生产效率，必须对实际生产过程中的主要参数，比如电压、温度、压力、水流、速度等进行有效的控制，其中温度控制在生产过程中起着至关重要的作用。准确地测量温度并且有效地控制温度
