Abstract
Disclosed is a control method of a damper of a variable-air-volume air distributor and a control system thereof, mainly comprising a volume adjusting valve for the variable-air-volume air distributor, a valve actuator, a BP neural network-based main controller, a data collector and a user operation panel. The control method thereof is to use, mainly based on the collected room temperature and static pressure at the inlet of the air distributor, the BP neural network predictive model to establish a nonlinear model of temperature & static pressure and valve opening, perform training and optimization, and optimize the output valve opening to obtain and label an optimal value as the set value of the controller to control the action of the valve actuator, thereby realizing an automatic variable air volume.
