| Abstract: | The problems of modelling and controlling of two stage heat exchange unit in the thermal station of centralized heating sys tem are investigated and a dynamic mathematical model of the heat exchanger uni t is developed. A method of modelling in time domain is adopted in the process o f modelling and meantime certain rational conversion is performed for the solid heat transfer medium in the heat exchanger. A combined control strategy of Bang Bang and PID controls is adopted for the control of the unit, and its computer simulation shows that this controller possesses good fastness, good robustness, and comprehensive control quality. |
