Comparison between Model Predictive Control and Smith Predictor with PID Approach for Chamber Pressure in a Coke Furnace

This paper describes the comparison of smith predictor with PID and model predictive controller (MPC). In a coke furnace the dynamic relationship between the input and output device is complicated. Since the performance is closely related to the control used and also improved control alternatives are necessary. The control target is to maintain the chamber pressure of coke furnace with in a set range while rejecting the effect of disturbances. The proposed controllers tested on the process model of the SISO system with FOPDT model. Simulation results shows the effectiveness of the both proposed methods
