Abstract

An adaptive controller is designed for the nonlinear MIMO heating, ventilating, and air conditioning (HVAC) system. The designed controller has the ability to adapt to the slowly time varying load change of thermal space and maintains good tracking performance for temperature and humidity ratio. Moreover, we integrate a supervisory switching logic into this system to adjust the CO₂ concentration of thermal space and the whole closed loop system is modelled as a hybrid system. The obtained control system shows robustness and effectiveness and simulation results are provided to illustrate the control performance
