Abstract

When shared, band-limited, real-time communication networks are employed in a control system to exchange information between spatially distributed components, such as controllers, actuators, and sensors, it is categorized as a networked control system (NCS). The primary advantages of a NCS are reduced complexity and wiring, reduced design and implementation cost, ease of system maintenance and modification, and efficient data sharing. In addition, this unique architecture creates a way to connect the cyberspace to the physical space for remote operation of systems. The NCS architecture allows for performing more complex tasks, but also requires taking the network effects into account when designing control laws and stability conditions. In this entry, we review significant results on the architecture and stability analysis of a NCS. The results presented address communication network-induced challenges such as time delays, scheduling, and information packet dropouts.
