Control Loop
A control loop is a fundamental concept in automation where a system continuously monitors an output, compares it to a desired setpoint, and then adjusts an input to minimize the difference. It's how automated systems maintain desired conditions.
TECHNICAL DEFINITION
A control loop is a fundamental feedback mechanism in automation and control systems, comprising a sensor measuring a process variable, a controller comparing it to a setpoint, and an actuator adjusting a manipulated variable to minimize the error and maintain the system at the desired state.
BACKGROUND
Computer numerical control (CNC) or CNC machining is the automated control of machine tools by a computer. It is an evolution of numerical control (NC), where machine tools are directly managed by data storage media such as punched cards or punched tape. Because CNC allows for easier programming, modification, and real-time adjustments, it has gradually replaced NC as computing costs declined.
