摘　　要：针对啤酒发酵过程温度控制的大惯性、时滞及非线性等特点,在传统模糊PID控制算法的基础上引入变论域的思路,设计一种变论域模糊自适应PID控制器,可动态改变模糊控制器输入和输出的论域范围。实验数据表明,所设计的控制器具有超调量小、稳态精度高、动态调节能力强等优点。In view of the features such as great inertia, time-lag and nonlinear etc. for temperature control in the process of beer fermentation, the idea of variable universe based on traditional fuzzy PID control algorithm was introduced in this study and the variable universe fuzzy adaptive PID controller had been designed, which could dynamically alterate the input and the output domain range of the fuzzy controller. The experimen- tal data proved that the designed controller had the advantages of less overshoot, high steady precision and strong dynamic adjustment.
