Application of Improved Grey Predictive Control in Alcohol Temperature Control

Temperature in the fermentation process directly affect wine quality and yield. Commonly used in the actual production of ordinary PID control of temperature, method is simple, convenient, the most widely used. But for the fermentation process nonlinear, time-varying uncertainty and large delay, it is difficult to establish accurate mathematical model, PID control algorithm to control the quality is not very high, especially in error as the basic adjustment items, derivative action is only apparent in the system deviation function, is after the control, it cannot very well overshoot suppression system.
