Components of Closed Loop Control System
- Reference input : Reference point is also known as setpoint. Input signal provided by the signal. This is the target output that the system is designed to follow.
- Error Detector : It compares the signal obtained from feedback and the reference input. The error detector is a crucial component in a closed-loop control system. Its primary function is to measure the difference between the desired or reference input (setpoint) and the actual output of the system, generating an error signal.
- Controller: It is the element which produces the desired output from the actuating signal. The controller is a crucial component that calculates the corrective action needed to minimize the error and bring the system output closer to the setpoint.
- Process: The plant or process represents the system being controlled. It could be a physical system like a motor, chemical process, or any other dynamic system. It is the device to be controlled.
- Controlled output: It is the quantity which required to be controlled out the desired level. The controlled output is the parameter or variable that the control system aims to control and regulate.
- Feedback : It is the part of the output signal which fed to the error detector for comparison with reference input. This information is then compared to the reference input to determine the error, which is the difference between the desired and actual outputs.
Closed-Loop Control System
In this article, weâre going to discuss about closed loop control system. A closed-loop control system is an electronic device that automatically regulates a system to maintain a desired state or set point without human interaction. The advantages of closed-loop control systems lie in their ability to provide precision, stability, and resilience, making them indispensable in numerous technological advancements and industrial processes. The term âclosed-loopâ reflects the feedback loop that is established, where the output is fed back to the systemâs input for constant monitoring and correction.
