Distributed control system

Definition

A distributed control system (DCS) is a control system that uses distributed elements to monitor and control physical processes, often in large-scale operations such as power generation. In CSP systems, a DCS is crucial as it allows for decentralized control of various components, leading to improved efficiency and reliability in managing energy output and system performance.
