Control loop performance analysis over networked control systems

In this paper we discuss the suitability of standard discrete-time control models for the analysis and design of control loops implemented over networked control systems. In fact, depending on the specific control loop topology, different control approaches may apply. We distinguish between control approaches that offer synchronous and asynchronous actuation. Through simulation results we show that the performance of control loops closed over communication networks can be improved using approaches that support asynchronous actuation. This leads us to conclude that there is a need for more control approaches relying on the asynchronous actuation paradigm.
