外文摘要：The v?iable refrigerant volume (VRV) air conditioning systems have been employed in small and medium sized buildings recently for its advantages of comfort, energy conservation and easy maintenance. However, the optimal control of VRV air conditioning systems is very difficult due to cross-coupling system p?ameters and time-v?iant operating conditions. In this paper, the indoor temperatures ?e taken as the controlled v?iables to regulate the openings of individual electronic expansion valve (EEV) and the suction pressure is taken to modulate the speed of inverter-driven compressor, a robust and self-adaptive two-stage Fuzzy Proportional Integral Derivative (PID) controller is proposed. The controllability is tested in a triple evaporator VRV air conditioning system, experimental results show that the proposed two-stage fuzzy PID controller could achieve desired control accuracy and gu?antee good robustness for room temperature control. ? 2009 IEEE.
