Predictive control algorithm for integrating plant

DMC couldn't control integrating plant,because truncated errors would be brought. According to the characteristic that final trend of a step response for integrating plant was line movement, a model predictive control algorithm was presented based on a step response, truncated errors of DMC predictive model could be avoided by use of this algorithm. The results of simulations show,the result of this algorithm follow well the tracks of setpoint , this algorithm have good robust performance for model parameter perturbation,and this algorithm be practicable for integrating plant control.
