The Application of Cascade Control Based on DMC in Stripping Section Temperature Control System

Abstract:

Predictive control is one of the robust control algorithms that suitable for computerized implementation, and requests lower accuracy of the model. It has been widely used in process control recently. Considering the features of distillation column stripping section, such as complex internal mechanism, time-varying parameters and large time delay, the DMC-PID cascade control strategy is adopted. The simulation results show that this strategy combined the advantages of predictive control and cascade control, can make distillation column stripping section have good dynamic and static characteristic in the presence of external disturbance and time delay. The performances are better than DMC and conventional PID control.
