For the air-treating units with dynamic characteristic of large time delay and inertia in a heating, ventilation and air-conditioning system, a control system of fractional order PIλDμis proposed by synthesizing the theories of fractional modeling and automatic control. Air handling unit is established. Secondly, the corresponding control parameters are obtained by the approaches of frequency domain analysis and order number search. Accordingly, a control system of fractional order PIλDμfor air-handling unit can be designed and be verified via an example simulation. The results show that this control system is feasible in theory. Moreover, its control performance is better than that of the control system of traditional PID and further improve the service life of air handling unit.
