Synergetic control for HVAC system control and VAV box fault compensation
Radhia Ettouil, Karim Chabir, Dominique Sauter, Mohamed Naceur Abdelkrim
Abstract
Synergetic control is proposed for heating, ventilating and air-conditioning (HVAC) system control. The synergetic controller
is developed using the nonlinear model of the HVAC system. Occupancy information in each zone is required in the
design of the controller which offers inherent comfort according to the occupancy in the zone. The stability of the building
system using the proposed control is verified through the Lyapunov approach. It is also proved that the synergetic controller
is robust to external disturbances. Then, synergetic theories are used to design a reconfigurable control for damper
stuck failures in variable air volume (VAV) to recover the nominal performance. Simulations are provided to validate the
effectiveness of the proposed controller for a three-zone building.
