Motor drive load damping

摘要

An electric power supply system (20) has a power bus (30) for providing DC power, and a control unit (26) for a source (24) of power to supply the power bus. The control unit includes a damping algorithm to provide damping to power supplied on the power bus. A motor (260) and a motor control (34) include a compensation block (234) for tapping power from the bus, and identifying a portion of a supplied signal due to the damping. The compensation block provides a signal to a summing block (236) that addresses the damping on the power bus prior to the power being supplied to the motor. A method of utilizing such a system is also disclosed.
