Research On Fuzzy PID Control Of Heat Supply System

In the supply heat system, the pattern of supplying heat by minitype boiler is more general which cause serious energy source waste. It is more efficient to perform the function of autocontrol save energy only though adopting the approach of the whole heat-supplied process's autocontrol. So, It is important to study the autocontrol adapting to the heat-supplied system by minitype boiler.We can decide the control mode, and complete the control of boiler parameter, such as the temperature of feedwater, circle water measure, and so on. At the same time, adopting the combination of tradition PID controller and Fuzzy logical controller to enhance adaptive quality, robust quality and increate control precision. Successfully complete the autocontrol of the whole process from boiler to exchange heat station , and solve the discrepancy between stabilization of boiler's heat-load and real-time adjustment.Sun Wen-lai (control theory and control engineering)Directed by prof.
