Open loop vs closed loop gain

Web4 de dez. de 2012 · Open loop vs closed loop. By Norbert Benei ZI5A58. Open-loop . An open-loop controller, also called a non-feedback controller, is a type of controller which computes its input into a system using only the current state and its model of the system. . Open-loop. Slideshow 998120 by naava WebClosed-loop control uses the real-time position and stator current feedback to tune the speed controller and the current controller and change the duty cycles of the inverter. This ensures that the corrected three-phase voltage supply (that runs the motor) corrects the motor feedback deviation from the desired value.
