摘 要：A large-scale Variable Air Volume（VAV）air-conditioning system composed of several subsystems is ***’s a multi-variable,strongly coupled,time variant,nonlinear and large time delay *** system is wholly analyzed with large-scale system theory（LSST）in this *** learning control（ILC）is adopted to solve the problems of long steady-state time and large overshoot when set-points *** system is divided based on decomposition and coordination *** steady-state and energy consumption models are built for global optimal *** the evaluation of the large scale hierarchical control system theory,ILC and steady-state optimization strategy（LSHC-ILC-SO）,a case is studied on the VAV experimental *** results show that all devices work under coordinated conditions with coordination strategy under variable *** global steady state optimization can reduce the total energy consumption.
