摘　　要：The application of heating load prediction and predictive control to the heat supply system for energy saving and high quality heat supply is discussed by first introducing the time series prediction principle, and the sequence model, parameter identification and least variance prediction principle, and then giving the heating load and model error prediction based on this principle. As an improvement of DMC algorithm, the load prediction is used as a set point of DMC, and the prediction error is used as a corrected value of predictive control. Finally, the simulation results of two prediction methods to heat supply system are given.The application of heating load prediction and predictive control to the heat supply system for energy saving and high quality heat supply is discussed by first introducing the time series prediction principle, and the sequence model, parameter identification and least variance prediction principle, and then giving the heating load and model error prediction based on this principle.
