A survey - Networked control systems

Abstract

In the recent years the data network usage in a control system has gained attentions due to its flexible and cost effective applications. The major challenges in this so-called Networked Control System (NCS) are the packet losses and network-induced delay in the control loop. These challenges degrade the NCS control performance and destabilize the system. To handle these problems a significant emphasis has been on designing and developing control methodologies. This paper presents a overview on NCS structures, description of network delays including characteristics and its effects, and a detailed survey on the recent NCS control techniques.
