Investigation of Parameters Affecting Predictive Controller Performance for Boiler Turbine

The predictive control system decides the discrete moves in manipulated variables on basis of the prediction of output of the process upto the prediction horizon. The predictive controllers show an excellent performance as compared to conventional controllers. In the present work, a boiler turbine process with two manipulated variables and two controlled variables has been considered and a predictive controller has been designed for it. The impact of variation in the value of sampling interval, prediction horizon and control horizon on the setpoint tracking performance and the disturbance rejection performance has been investigated.
