How a Process Control Loop Works in Automatic Control ,

The final element in the control loop is a control element that exerts a direct influence on the process; it is the device that provides those required changes in the controlled variable to bring it to the setpoint This element accepts an input from the controller, which is then transformed into some proportional operation performed on the ,
