Model Based Networked Control Systems: A Discrete Time Lifting Approach

In recent years, control networks have been replacing traditional point-to-point wired systems. In networked control systems, the different elements, plants, controllers, sensors, and actuators are connected through a digital communication network with limited bandwidth. The new challenges that this implementation has brought are well documented. Perhaps the most relevant is the limitation on bandwidth; many researchers have studied different problems related to bandwidth restrictions such the state estimation problem under limited network capacity or the minimum bit rate required to stabilize a Network Control System (NCS). Other authors have focused on reducing network communication maintaining the system stable or keeping some level of performance.
