Lp stability of networked control systems

Results on input-output L_p stability of networked control systems (NCS) are presented for a large class of network scheduling protocols. It is shown that static protocols and a considered dynamical protocol called try-once-discard (TOD) belong to this class. Our results provide a unifying framework for generating new scheduling protocols that preserve L_p stability properties of the system if a design parameter is chosen sufficiently small. Our results are always guaranteed to be less conservative than existing results in the literature and we illustrate this via an example of a batch reactor.
