发酵罐温度的模糊预测控制方法

Fuzzy Predictive Controlling Method of Fermentation Tank Temperature

白酒发酵过程具有非线性、滞后等特性,而常规PID控制和模糊控制属于事后控制,难以实现精准控制,该模糊预测控制方法将模糊和预测控制策略的优势集中起来,设计出满足需求的模糊预测控制器,并运用到实际生产中。使用MATLAB的SIMULINK模块进行比较性模拟仿真。仿真结果表明,该设计方法可以较好地适应发酵过程的复杂环境,具有提高控制精度和响应时间的效果,在发酵过程控制中具有实用价值。

Because of the nonlinear and time lag of the fermentation process, meanwhile and the difficulty of the conventional PID control in the precise control in solving practical problems, the paper put forward a fuzzy predictive controlling method, by combining the advantages of fuzzy control and predictive control for systems. Using MATLAB SIMUI.INK module and comparative simulation, simulation results show that the proposed design method can better adapt to the fermentation the environment, improve the con trol accuracy and response time effect, and has a practical value in the fermentation process control.
