The Control On VAV System In The Intelligent Building

In recent years, the rapid development of intelligent buildings in our country, but the attendant problem of enormous energy consumption has caused concern around the world. VAV(Variable Air Volume) air conditioning system for its comfort, energy efficiency and flexibility began to be widely used in the air conditioning system, and gradually become the mainstream of the air conditioning system.However, due to VAV air-conditioning system in our country use, failed to achieve the desired results, in addition to part of engineering reasons, but also with the user's background and habits. Meanwhile, due to the VAV system itself strong coupling, multivariable and nonlinear characteristics, poor quality of the final results of its control, its popularization and application caused some impact.In this thesis, project examples VAV carried out research, by collecting debugging parameters for unstable stage of the project VAV systems, VAV system for changing the coupling characteristics related research expanded, and then come to the neural network-based solution decoupling of VAV system control program based on the decoupling deeper completed neuron adaptive PID controller design. At the same time, the use of traditional PID control algorithm parameter determines the initial value of the controller weights. Confirmed that the control method has significant advantages, can meet the requirements of energy saving and comfort, a good control effectFinally, from an engineering example, introduces a VAV terminal control system manufacturer, and discuss implementation...
