Abstract

This paper introduces a novel concept in torque analysis and torque controller design, using motor identity. The concept of identity is defined and analysis for generating an optimal input current which can produce smooth and maximum torque output is described. The extraction process of identity from a motor is also provided. Simulations and experiments applying this identity concept in torque control on a permanent magnet synchronous motor are given. The results are compared with a conventional motor controller using 3-phase sinusoidal currents
