METHOD AND APPARATUS FOR CONTROLLING THE CURRENT FLOW OF AT LEAST ONE PHASE WINDING OF A SWITCHED RELUCTANCE MOTOR

摘要

The invention relates to an apparatus and method for controlling the current flow of at least one phase winding of a switched reluctance motor during at least one dwell period of the motor, wherein the dwell period starts with a turn-on angle of the motor and ends with a turn-off angle of the motor. The dwell period is divided in a first subinterval comprising a first reference current, a second subinterval comprising a second reference current, and a third subinterval comprising a third reference current wherein the flow of the first reference current is controlled based on at least one or more motor-efficiency parameter which depends on the efficiency of the motor, the flow of the second reference current is controlled based on at least one or more torque-parameter which depends on the torque of the motor to control the torque production of the motor, and/or the flow of the third reference current is controlled based on at least one or more noise and/or vibration parameter which depends on an electromagnetic force produced by the motor to reduce noise and/or vibration of the motor.
