Abstract
The present disclosure provides a system and method that provides active damping at the input of a motor drive system without the need for the hardware used in conventional and RC damping circuits. According to the disclosure a virtual damping network is realised at the input of the motor drive system based on modification of field-oriented control, FOC. More specifically, a control algorithm creates a virtual damping impedance at the motor drive input by applying a damping algorithm to both q and d components of the motor current.
