| Abstract |
After analyzing the behavioral properties of a current-fed synchronous motor operating at
variable speed in an open-loop mode, we demonstrate herein the performance of an open-loop control
in the abc reference frame. Oscillation problems observed in the torque are solved by applying a
control in an estimated reference frame dq. Due to inaccuracies in the model however, the use of a
basic device that provides one impulse per revolution seems to represent an effective arrangement
between a synchronous mode control and a classical sensor-free control. Within the control scheme
of an energy storage system, two control loops are necessary (current and power). The subject of this
work is confined to just the current control. The model used is then validated by experiment. |
