Event-triggered and networked control systems
The project is focussed on how to design networked control systems such that certain stability and performance requirements of the control loop are guaranteed while shared communication networks are present in the loop, and on reducing the load on the communication networks by using event-triggered control.

In traditional control systems the sensors and actuators of the plant are each connected to the controller via a dedicated wired link. However, actuators, sensors and controllers are increasingly connected to each other via shared wired or even wireless communication networks, resulting in so-called networked control systems (NCSs). This offers advantages such as reduced installation cost, better maintainability and increased flexibility. Next to these advantages, NCSs are adversely affected by several network effects, including varying transmission intervals and delays, quantization errors and packet losses
This research is focussed on how to design NCSs such that certain stability and performance requirements of the control loop can be guaranteed, even in the presence of the aformentioned network effects.
Furthermore, control strategies are investigated that reduce the load on the communication networks by only transmitting information when that is really necessary in order to guarantee certain control performance, so-called event-triggered control (ETC).
