closed-loop feedback control system
Quick Summary
A closed-loop feedback control system is a technology that regulates an operation or process by using feedback. This means the system monitors its own output and uses that information to make adjustments to maintain a desired state.1
The core components of a feedback control system include:
* Input: The desired value or set point.
* Process: The operation or mechanism being controlled (e.g., a heater, an engine).
* Output: The actual measured value of the process.
* Sensing Elements: Devices that measure the output.
* Controller and Actuating Devices: These compare the output to the input and make necessary adjustments to the process.2
Unlike open-loop systems, which operate without monitoring their output, closed-loop systems continuously adapt to ensure the output matches the desired input, making them highly effective for automation.32
