An Air Balancing Method based on Distributed Finite-Time Control for the Ventilation Duct System

Testing, Adjusting and Balancing (TAB procedure) is an important issue of air distribution systems. This paper proposes a distributed finite-time control-based air balancing (DFTC-AB) method for the ventilation duct system. It is employed by using the distributed finite-time control approach which can achieve air balance via exchanging information with neighboring terminals. Comparing with the traditional air balancing methods, the proposed DTFC-AB method has the following advantages. 1.) This method only need to communicate with neighboring terminals, thus eliminating the necessity of a centralized control unit. 2.) It is mode-free method that requires no system topology and parameters and is therefore easy to apply. 3.) The proposed method has a better convergence performance, which can reduce the convergence time. The experiment results verified the performances of the proposed method.
