摘　　要：针对目前汽车油漆喷涂温度采用管中管的方式,在利用传统PID进行温度调节,引入模糊控制的情况下对PID功能块进行优化,根据不同的工况优化控制模式。基于现场已有的工程经验数据,利用Simulink对热交换系统的比例阀进行建模仿真,将仿真优化后的参数应用到实际生产线进行验证,改进后的参数在温度出现变化时对喷涂温度的调节更加稳定,现场温度始终保持在设定温度值22℃±1℃范围内变化。基于现场实际工况开发的PID集成功能块,相比于传统的PID功能块具有较高的实用性。For the current automotive paint spraying temperature using pipe-in-pipe,the use of traditional PID for temperature regulation,the introduction of fuzzy control in the case of the optimization of the PID function block,according to the optimization of the control mode of different working conditions.Based on the existing engineering experience data in the field,the proportional valve of the heat exchange system is modeled and simulated using Simulink,and the optimized parameters are applied to the actual production line for verification,and the improved parameters are more stable in the regulation of the spraying temperature when there is a change in the temperature,and the field temperature is always kept in the range of the set temperature value of 22℃±1℃.The PID integrated function block developed based on the actual working conditions in the field has higher practicability than the traditional PID function block.
