Closed-loop control is a system that automatically adjusts its operation based on feedback from the output. This means that it continuously monitors the results of its actions and makes changes to achieve the desired outcome. For example, a thermostat regulates room temperature by comparing the current temperature to the set point and adjusting the heating or cooling accordingly. In a closed-loop control system, the feedback loop is essential for maintaining stability and accuracy. By using sensors to gather data, the system can correct any deviations from the target. This approach is commonly used in various applications, such as automated manufacturing, robotics, and climate control systems.
