This paper proposes the dynamic matrix control of heat supply object based on the feature of heat supply process.The use of simplified model and prediction error correction improves conventional control algorithm.It introduces the principle of model simplification

and derives immediate control.In order to compensate model mismatch after simplification

the prediction model error is used to replace model error to carrly out correction of optimum control of system.The prediction error correction is based on time series analysis

parameters estimation and optimum prediction principle.In the end of the paper

simulation of heat supply object about above-mentioned algorithm is carried out.Simulation results prove that algorithm is effective in ensuring real-time control

improvement of tracking and robustness property.
