Decentralized controllers for wireless networked building automation system

Building Automation System (BAS) is drawing the attention of research community worldwide as it implies the efficient energy management of buildings. The distributed sensors, controllers and actuators in various BAS zones could be connected over a wireless network, forming the closed loop control. However, building automation based on wireless systems raises issues for the real-time communication of sensor data and control commands through the channel with a guarantee on control effectiveness. Hence it is ample to develop techniques that can be used to improve the robustness of the control systems which communicate by multiplexing the available channel. In this paper, a decentralized Wireless Networked Control System (WNCS) architecture is proposed for BAS and decentralized controller design techniques for ensuring the stability of the closed loop control of BAS in the presence of network uncertainties.
