Rotor position sensorless control of the switched reluctance motor drive for the direct-drive joint of the robot

Abstract

The paper presents the principles of the rotor position sensorless control of switched reluctance motor drive system. The input control parameters, such as the variation of the phase current and the rotor speed, are described. The fuzzy logic algorithm for calculation of the rotor position is introduced. The hardware, the software and the scheme of current detector are given.
