摘　　要：为提高金属压力加工质量,解决现有温度控制系统存在控制性能差的问题,设计金属压力加工补偿温度自动控制系统。改装温度传感器、补偿温度模糊控制器、加热与制冷装置,利用系统电路将改装硬件与原硬件连接,完成硬件设计。根据金属压力加工原理,构建金属压力加工热力学模型,选择最佳温度测点;利用温度传感器设备自动采集各测点实时温度,计算金属压力加工温度补偿量。在模糊控制器支持下,实现金属压力加工补偿温度自动控制。实验结果表明:设计系统温度控制误差低于1.0℃,运行时间开销低于8000 ms。In order to improve the quality of metal pressure machining and solve the problem of poor control performance of the existing temperature control system,an automatic temperature control system for metal pressure machining compensation is designed.The temperature sensor,compensation temperature fuzzy controller and heating and cooling devices are refitted,and the system circuit is applied to connect the refitted hardware with the original one to complete the hardware design.According to the principle of metal pressure machining,the thermodynamic model of metal pressure machining is constructed,and the best temperature measuring point is selected.The temperature sensor equipment is used to automatically collect the real-time temperature of each measuring point and calculate the metal pressure processing temperature compensation.With the support of fuzzy controller,the automatic control of metal pressure machining compensation temperature is realized.The experimental results show that the temperature control error of the designed system is less than 1.0℃and the running time overhead is less than 8000 ms.
