Modeling of Networked Control Systems in Electric Multiple Unit with Packet Dropout and Network-Induced Delay

Abstract

In this paper, a modeling method is presented for networked control systems (NCSs) of electric multiple units (EMUs) with packet dropout and network-induced delay. It is assumed that the induced delay is less than the sampling period T, and the event rates (scilicet, the data packets transfer successfully rates) are fixed. The NCSs in EMUs can be described as an asynchronous dynamical systems which are driven by "events" that occur asynchronously. Using the dynamic output feedback control method, the systems exponential stability is discussed when the system state is not acquirable.
