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 the turn-off angle of the motor, wherein 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 motor-efficiency parameter which depends on the efficiency of the motor, and wherein the flow of the second reference current is controlled based on at least one torque-parameter which depends on the torque of the motor to control the torque production of the motor.
