WebOpen-loop control (also known as scalar control or Volts/Hz control) is a popular motor control technique that you can use to run any AC motor. This is a simple technique that does not need any feedback from the motor. To keep the stator magnetic flux constant, we keep the supply voltage amplitude proportional to its frequency. Web24 de fev. de 2012 · An open-loop control system can be converted into a closed loop control system by providing feedback. This feedback automatically makes suitable changes in the output due to external disturbance. In this way, a closed loop control system is called an automatic control system.
