Application of Multivariable Model Prediction Control to Ultra-supercritical Unit

In this paper, development of ultra supercritical unit control is summarized. Based on analyzing the control difficulties and the input-output relationship of Ultra-supercritical Units, a model predictive control scheme for Ultra-supercritical Unit is proposed. The input variables are fuel flow, turbine valve opening and water flow and output variables are load, steam temperatureteam pressure. The algorithm and implementation method are also given in details.
