Novel advances in Networked Control Systems (NCSs)

In this project we seek for novel modeling and analyzing approaches to model complex systems that utilize packet-based communication networks for the exchange of information. By exploiting new analyzing techniques for hybrid systems, performance guarantees are derived for such NCSs.

In many applications, sensor and actuator data is communicated over a shared (wired or wireless) packet-based communication network. Such systems are often referred to as networked control systems (NCSs) and have received considerable attention in recent years as they offer many advantages when compared to conventional control systems in which sensor and actuation data is transmitted over dedicated point-to-point (wired) links. On the other side, the usage of packet-based networked communication comes also with the inevitable network induced imperfections, such as varying delays, dropouts, varying transmission intervals, and so on. To deal with all these networked-induced phenomena, the NCSs are often modeled as hybrid inclusions.

This research in particularly focuses on developing new modeling and analyzing methods for such NCSs such that a larger amount of applications can be modeled according to this framework. By introducing new analyzing techniques for hybrid systems, conditions are derived to guarantee certain stability and performance requirements. Moreover, so-called event-triggered control strategies are investigated to reduce the amount of transmissions needed while still guaranteeing the same control performance properties.
