Method and apparatus for quasi sensorless adaptive control of switched reluctance motor drive

摘要

Problem to be solved: to provide a method and apparatus for quasi sensorless adaptive control of a multi rotor pole switched reluctance motor (hrsrm).The method includes applying a voltage pulse to the inactive phase winding and a step 110 for measuring the current response of each inactive active winding.A motor index pulse is used for speed calculation 114 to establish a time base.The gradient of the current is continuously monitored so that the speed of the shaft can be updated several times and the speed of any speed can be tracked and 126 to determine the Doel angle based on the shaft speed.An apparatus for quasi sensorless control of a multi rotor pole switched reluctance motor (hrsrm) is a switched reluctance motor having a stator and a rotor, and a three-phase inverter controlled by a processor connected to a switched reluctance motor; Load and converter including.Diagram
