Experimental implementation of a networked input-output sporadic control system

Event-based control (EBC) is growing in importance since this paradigm leads to a better integration with networked systems. Particularly due to the distributed and asynchronous inherent nature of such systems. The reported main advantage is the reduction of the control rate allowing a less saturated communication network. This fact has been proved with different EBC schemes, as using impulse control schemes within stochastic environments and different PID structures. In this work, the experimental study of an event based input-output control scheme is presented, following the sporadic control approach and implemented in a networked environment. In this scenario, noise minimizes the advantages of event-based schemes. The use of a filtering strategy minimizes its effect, restoring the reduction of the control rate. This kind of approach leads to interesting practical applications. Simulation and experimental results show the performance of the control approach under study.
