Guest Editorial
Special Issue on Networked Control Systems
MOTIVATED by the accelerating technological conver-
gence of communications, control, and computing,
researchers from a variety of disciplines have become inter-
ested in the exciting potential and technological challenges of
networked control systems (NCSs). In the broadest terms, these
systems are comprised of actuators, sensors, and controllers
whose operation is coordinated through some form of commu-
nication network. The system elements are typically spatially
isolated from one another, operating in an asynchronous
manner and communicating over a wide area via both wired
and wireless links.
While work to build the foundations of networked control
systems technology has accelerated in both industrial and uni-
versity research centers, many fundamental questions regarding
stable operation of interconnected hard real-time systems, signal
coding and control information flow, peer-to-peer networking,
effects of the network on the performance of control systems,
