The Temperature Control Based on the AHU of Fuzzy-PID

Abstract:

Air conditioner unit which is a significant part of central air-conditioning is a multiinput-multioutput system.Because the input quantity of it is related with each other and influenced by multifarious interference, an ideal control effect is unavailable by general control method. It is also the main unit of energy consumption, so the refrigeration effect and the energy consumption of the central air-conditioning are determined by the control effect and efficiency of it. A neural network model is made according to the unit of air handing and controlled by the strategy of fuzzy-PID. It is proved by experiment that favorable control effect is available in case that the fuzzy-PID control strategy meets requirements when either there is interference or the target quantity changes.
