Adaptive Control Strategy for the Online Decoupling Control of the Variable Flow Rate HVAC System
The heating,ventilation,and air conditioning(HVAC)system operates under complex conditions with high uncertainty.During the decoupling control of system quality-quantity parameters,traditional periodic control strategies struggle to respond promptly to random load variations,resulting in suboptimal decoupling control effect.Therefore,this paper proposed an event-driven decoupling control strategy to improve the overall control performance of the system.This method identifies the key parameters that affect system performance and comprehensively considers the dynamic response characteristics of system quality-quantity parameters,which can reset the setpoints of control loops at appropriate time to achieve global optimization control.In comparison with the conventional strategy experimentally,the proposed strategy has significant advantages in terms of operating conditions adaptability,decoupling and control effect,and can also save approximately 3.4％of electricity consumption.
