Study on Simulation of Dynamic Matrix Control for Heating System

This paper presents predictive control scheme of heat supply system based on the demand of energy saving of building heat supply and of the feature of heat supply object. First, it introduces basic dynamic matrix control algorithm (DMC), and gives the constitute of predictive model, rolling optimization and error correction. Next, in order to enhance real-time property, DMC simplification algorithm is analyzed and given. Then, it is presented to use predication error correction to replace general error correction in dynamic matrix control based on time series analysis method. Finally, the effectiveness of algorithms is illustrated by simulation results.
