Direct torque control algorithm of asynchronous traction motors on the locomotive with eighteen-corner stator flux locus

Abstract

This paper proposes a model of DTC system with Eighteen-corner
stator flux locus of asynchronous traction motors on locomotives. The
advantages of this method are its simplification, fast dynamic
response, and low dependence on motor parameters. Its effectiveness
and feasibility are demonstrated by both theoretical analysis and
experimental results.
