本文針對啤酒發酵過程具有時變、大慣性、時滯和非線性的特點，提出了啤酒發酵溫度
的自動控制模型。模型采用了基于操作經驗、基于過程模糊模型和基于學習的自整定模糊PID 控制算法，并帶有模糊模型辨識和史密斯預估補償算法。該控制算法在基于Profibus-DP的分布式計算機控制系統上實現并在遼寧撫順天湖啤酒有限公司投入使用，取得非常理想的控制效果和經濟效益。

Abstract: An auto-control model is presented to the process of beer fermentation, which has the characteristics such as time-varying, inertia, time-delay and nonlinear. In the model, the control adopts self-tuning fuzzy PID control arithmetic which is based on operation experience, process fuzzy model and study, and appends with fuzzy model identification and Smith pre-estimated compensation arithmetic. The control model proposed in this paper is implemented on the control system which is combined with programmable logic controller and based on Profibus-DP distributed I/O station ET200M, and is applied in Tianhu beer Limited company in Fushun, Liaoning, and also obtains perfect control effect and economic benefits.
