Real time distributed system with smart agents that can communicate and interact with environment through a common communication medium is called a Networked Control System (NCS). Dependency on communication systems increases, the bandwidth of medium became the hindrance to the Networked Control System. This led the researchers to focus on control systems, apart from communication networks. Prominent challenges in integrating control and communication are network induced delay, packet dropouts, scheduling strategies, network load, efficient bandwidth utilization, stability and desired characteristics of the system. This article focuses on the issues involved in the design and implementation of NCS from communication as well as control point of view. The different delays involved in NCS are analysed and proposed methods to overcome delays using compensator are also discussed.
Keywords: Maximum Allowable Delay Bound (MADB), Networked Induced Delay (NID), Networked Control system (NCS), Quality of Performance (QOP), Quality of Service (QOS)
