Abstract:

District heating process is a complicated dynamic and thermal nonlinear system. For controlling it the system model should be found firstly. Through the research and analysis of the knowledge about heating system, this paper on the basis of mechanism model, researched the establishment of experimental models. Firstly by measuring the response data, the model parameter identification of the heating process can be made to got the heating determining part model, then random part of the system model can be described by the method of Autoregressive Integrated Moving Average Model. Finally using the MATLAB to simulate and make the model step response curve analysis. Simulation results show the model is effective and verified.
