Title Design and Simulation of Electric Stove Fuzzy Controller
Abstract Temperature control in industrial control has been the subject of innovation, for different control objects, there are different control methods and models. Temperature control system is common in industrial production, but due to the inertia, the lag and the time-varying, it is difficult to establish the mathematical model. Fuzzy control is based on fuzzy math, which use language rules to represent methods and advanced computer technology, and it is an advanced control strategy which decision-make by the fuzzy inference. This article put electric boilers as the research object, use the fuzzy controller to control the system to meet system stability, short adjustment time, and small overshoot performance index. Thesis outline the history and the development of fuzzy control system, and it's basic knowledge of mathematics, the basic structure of the fuzzy logic controller and design methods, as well as several ways of MATLAB and C mixed programming. Finally, through the experiment, we analyze the affection of control parameters on the system.
