Webclosed loop control system: A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input. WebClosed systems have a life cycle: pre-use, in use, post-use. Despite being “closed,” systems must permit the addition, removal, and transfer of mass in a way that maintains system closure. Different processes have different closure requirements; the system should meet those requirements.
