摘　　要：针对啤酒发酵温控系统非线性、大时滞的特点,提出将靶向控温思想与模糊PID控制算法相结合,设计了基于靶向控温点实现控温的模糊PID控制器,以提高啤酒发酵温度控制的精确性。以西门子S7-400PLC和Braumat软件平台为控制核心,设计啤酒发酵温度控制系统软硬件结构,实现对整个生产过程的控制与监测。现场实际应用表明:啤酒发酵温度控制误差为±0.3℃,控温效果好,满足实际生产要求。According to the characteristics of non-linear and large time delay in the temperature control system of beer fermentation,proposed the idea of target temperature control combined with fuzzy PID control algorithm,and designed a fuzzy PID controller based on target temperature control point to achieve temperature control,so as to improve the accuracy of temperature control of beer fermentation.Taking Siemens S7-400 PLC and Braumat software platform as the control core,the software and hardware structure of beer fermentation temperature control system was designed to realize the control and monitoring of the whole production process.The field application shows that the temperature control error of beer fermentation is±0.3℃,and the temperature control effect is good,which meets the actual production requirements.
