一种基于模糊控制的温度控制系统设计

Design of a Temperature Control System Based on Fuzzy Control

为提高工业上所需温度的控制精度,文中介绍了一种以STC89C52单片机为核心,采用模糊控制算法的温度控制系统,并对模糊控制思想,包括模糊控制的基本结构和参数设计,及系统的软、硬件设计进行了详细阐述。在该系统中,通过采用模糊控制算法对温度实现了很好的控制,并且该系统正处于实际工业电阻炉温度控制的应用和试行阶段,也达到了满意的控制效果。实践表明,模糊控制方法提高了控制的实时性稳定性和精确度,并且实现了操作过程的简化,对于工程实际应用具有较强的借鉴意义。

For improving the temperature control precision as the industry requires, a temperature control system, which takes STC89C52 singlechip as the core and adopts fuzzy control algorithm, has been presented, and the thinking of fuzzy control including the basic structure and the design of parameters as well as the design of software and hardware for the ,said system being expounded in detail. Using the algorithm of fuzzy control in the system, the temperature was controlled in good state. At present, the system has been used in the phase of the application and the pilot of the resistance furnace temperature in the actual industrial, and satisfying results were achieved. Practice shows that fuzzy control method improves the real - time performance,stability and accuracy of controlling and makes the operation simplified. The use for reference of the method was obviously in industrial application.
