Abstract:

The variable air volume has the characteristics of multivariable,strong coupling and delays.The traditional methods for the decoupling of the VAV are not effective.The paper corrects the decoupling controller further according to the traditional static decoupling method on the basis of the diagonal decoupling,achieving a better dynamic performance and robustness for the VAV of decoupling.A comparison with the method of simplified decoupling in the system of VAV is given.The result of Simulink shows the effectiveness and feasibility of the improved method.

Key words: VAV;multivariable;decoupling;dynamic performance
