+A control loop is a fundamental mechanism that continuously regulates a system's output toward a desired state. It measures the actual output, compares it to a [Set Point](/wiki/set_point), and adjusts the input to minimize the difference, forming a [Feedback](/wiki/feedback) path. This constant, iterative process ensures stability and precision in automated systems.
