摘　　要：针对啤酒生产线原系统运行时温度稳定性差等缺点,通过改用P-Fuzzy-PI控制,并结合在线参数自适应Smith补偿方案,对温度进行实时控制。结果表明,改造后温度稳定性提高,效果优于传统PID控制和单纯模糊控制。In order to get over the disadvantages of poor temperature stability of the PID system and single fuzzy system in original beer production line, the improved P-Fuzzy-PI combined with Smith compensation program （on-line parameter adaptive） was used to achieve real-time temperature control. The production practice proved that temperature stability had been improved and better effects had been achieved.
