Abstract

In this paper, a control strategy using Dynamic Matrix Control algorithm is proposed to enhance the already installed PID controller for the control of the coal flow delivered to the power plant boiler. The future control inputs are calculated by solving the quadratic optimization problem using Hildreth algorithm. Two cases are considered in testing and comparing the performance of the new DMC control strategy. The simulation results showed an improved control performance compared to the case of using the PID controller for mill dynamic responses.
