A Closed-Loop Control System is a type of control system that uses feedback to ensure the desired output is achieved. It continuously monitors the output and compares it to a set reference or target value. If there is any difference, or error, the system automatically adjusts its input to minimize this discrepancy, ensuring more accurate and stable performance. This system is commonly used in various applications, such as in thermostats for regulating temperature or in automated manufacturing processes. By utilizing feedback, closed-loop systems can adapt to changes and disturbances, making them more reliable than open-loop systems, which do not use feedback.
