Integral Control is a feedback mechanism used in control systems to eliminate steady-state error. It works by continuously adjusting the control output based on the accumulated error over time. This means that even small, persistent errors will eventually lead to a significant response, helping to bring the system closer to the desired setpoint. In practice, PID controllers often incorporate integral control as one of their components. By integrating the error, the controller can respond more effectively to changes and maintain stability in systems like temperature regulation or speed control in automated processes.
