The start control of heating system based on self-tuning

The problem of controlling the start-up of heating system is considered and the need for a self-tuning start control scheme is explained. The internal temperature change process of building is analyzed under the influence of heating source and external environment, and the change principle is found out. From the point of thermodynamics, the mathematical model of the process of intermittent heating is established on the basis of similitude principle. The self-tuning control strategy is introduced to finish the simulation and experiment of intermittent heating start, the results show that the self-tuning controller behaves well and has superior performance characteristics compared to two traditional methods.
