Summary: 1562 IEEE TRANSACTIONS ON AUTOMATIC CONTROL, VOL. 49, NO. 9, SEPTEMBER 2004
Stability of Model-Based Networked Control Systems
With Time-Varying Transmission Times
Luis A. Montestruque, Member, IEEE, and Panos Antsaklis, Fellow, IEEE
Abstract--In model-based networked control systems
(MB-NCSs), an explicit model of the plant is used to produce
an estimate of the plant state behavior between transmission
times. In this paper, the stability of MB-NCSs is studied when
the controller/actuator is updated with the sensor information
at nonconstant time intervals. Networked control systems with
transmission times that are varying either within a time interval or
are driven by a stochastic process with identically independently
distributed and Markov-chain driven transmission times are
studied. Sufficient conditions for Lyapunov stability are derived.
For stochastically modeled transmission times almost sure stability
and mean-square sufficient conditions for stability are introduced.
Index Terms--Model-based networked control systems
(MB-NCSs), stochastic stability, time-varying transmission
times.
