ABSTRACT
The convergence of computing, communication, and control enables integration of computational resources with the physical world under a concept of cyber- physical systems and is a major catalyst for future technology development. The postulate of providing wireless communication of a limited bandwidth between smart devices creates new challenges for networked sensor and control systems design, as the wireless transmission is energy expensive, while interconnected devices are often battery powered. The promise of saving communication bandwidth and energy resources is the primary motivation that stimulates research interest on event-triggered control strategies in networked systems. The average requirements of networked system communication bandwidth for a single control loop are defined by the mean number of send-on-delta samples per unit of time. In the context of control systems, the class of threshold- based sampling represents event-triggered sampling algorithms oriented to update the control law when needed to achieve a desired performance.
