Abstract :
The dynamic lag for the saccharification temperature process of brewage is very large, and the saccharification process technology needs its control track the set point curve fast without overshoot. The normal PID algorithm apparently can´t satisfy these demands. Due to the frequent disturbances of heating steam pressure, saccharification temperature DMC-PID cascade control system is designed by combining the predictive control algorithm and cascade control structure. The simulation shows that the system has not only faster follow-up tracking capability, but also non-overshoot and stronger disturbance suppressing, compared with the normal PID control.
