In a networked control system (NCS), sensors, actuators and controllers are spatially distributed and interconnected via a shared communication medium, i.e. control loops are closed via a real-time network. NCSs are essential and have become the standard in the automotive industry, avionic systems and automated manufacturing systems. The presence of the communication network inevitably introduces new challenges for the control engineering community that lie at the intersection of control and communication theory.

In this talk, I consider the robust communication schedule design problem. Given a plant and a controller, we are interested in designing a (sub)optimal communication policy between nodes that minimizes the performance degradation introduced by the network, in an H-infinity framework. The resulting combinatorial optimization problem is solved by fast stochastic algorithms.

A custom built hardware-in-the-loop rig and a FlexRay simulation setup, implementing a realistic automotive control system, are used as a testbed to validate the effectiveness of the design.
