摘　　要：提出了一种CPLD控制下的热处理电阻炉温度控制系统。通过对热处理工艺及常用箱式电阻炉工作原理进行分析,确定控制对象。然后利用ALTERA公司的5M160ZE64I5N型CPLD可编程逻辑器件作为核心,设计了硬件电路,同时耦合神经网络改进的PID算法作为核心的软件系统,完成了电阻炉温度控制系统的设计。最后设计了仿真实验,通过仿真实验表明,本文设计的电阻炉温度控制系统能对电阻炉加热温度进行实时有效的控制。A temperature control system of the heat treatment resistance furnace was proposed based on CPLD. The control object was determined by analyzing the working principle of the common box type resistance furnace. Then using the5M160ZE64I5 N CPLD programmable logic device of ALTERA company as the core, the hardware circuit was designed, at the same time, the PID algorithm improved by the coupled neural network was used as the core of the software system, and the design of the temperature control system was completed. Finally, the simulation experiment was designed, and the simulation results show that the designed temperature control system for resistance furnace can effectively control the temperature of the resistance furnace.
