模糊控制是利用模糊数学的基本思想和理论的控制方法。它可以不需要被控对象的数学模型即可实现较好的控制,因而特别适用于那些具有纯滞后、大惯性、参数漂移大的非线性不确定复杂系统,在鲁棒性和抗干扰能力方面有很大的优势。本设计将模糊控制算法引入传统的加热炉控制系统,从而构成智能模糊控制系统,将能很好地实现对温度的控制。其中关键的步骤在于设计模糊控制器,根据模糊控制规则进行模糊推理,并决策输出模糊量。最后,对结果进行计算机仿真,在MATLAB环境下进行,并绘制出温度响应曲线及控制量加热功率的变化曲线。6494

Title A design and simulation of fuzzy control algorithms on temperature
Abstract
The method of fuzzy control using fuzzy mathematics is the basic control method and the basic theory. Doing not need the mathematical model of controlled object, it can achieve better control. So it specially uses for nonlinear uncertain complex system with delay, large inertia, a large of drift parameter, which has great advantages in robustness and anti-jamming capability. This design, which constitutes the intelligent fuzzy control system, introduces the fuzzy control algorithms into the furnace control system. So it will be able to achieve better control on temperature. The key step is designing the fuzzy controller, reasoning based on fuzzy control rules, and decision-making the output fuzzy variable. Finally, simulate the result in the MATLAB environment with computer, draw the temperature response curve and control heating power curve.
