Some remarks on the stability of networked-control systems with periodic scheduling

This paper addresses some stability problems for networked control systems with periodic scheduling. The analysis of such systems is more complicated than single-sampling case as for example, the overall system may be stable even if some subsystems are unstable. In this context, it is important to understand how network-induced delays and hyper-samplings affect the stability of the overall system. Three particular stability problems involving constant and/or time-varying parameters are investigated, and the corresponding stability regions are derived.
