Coal mill is widely used in power plants in China. PID control is mainly used as the control method for coal mill to maintain steady boiler operation at various loads. Conventional PID control deteriorates when the load departs from the set point. Fuzzy PID control is suggested in this paper with further improvement by selflearning method.
Abstract: In recent years, the load following capability of thermal power plants has been actively researched, as power system interconnection unavoidably brings about complicated load variations. The key to improving the load following capability is the control of the fuel supply to the burner, which is provided by the coal mill.
