“…An unusual approach was demonstrated in [60,61], where the authors suggested to use maximum torque control (MTC) reference frame dmqm, where qm axis is aligned with the stator current vector at the MTPA angle. The authors considered steady stated mode of motor operation and redefined quadrature axis inductance in the new reference frame as:…”

This paper discusses the Maximum Torque Per Ampere (MTPA) control of synchronous motors, which have become an indispensable part of highly-efficient motor drives. It explains the nature of torque produced by synchronous motors, ways to find its maximum and algorithms to operate at this point, despite changes of loads and motor parameter variations. The authors propose a classification of the MTPA methods, based on the features of each algorithm or group of similar methods. They demonstrate the conventional control scheme and discuss the modifications necessary for the implementation of each method. This paper reviews existing maximum torque per ampere control algorithms, discusses their pros and cons and suggests possible areas of usage for each group of methods. The authors of the paper share their vast experience in the industry and research aspects, which were obtained by developing industrial, commercial, traction and military drives, and report on their views on the perspective of each method taken into consideration.

The importance of ultra high speed (≥ 50 krpm) motor technology has surfaced for various applications including turbo-compounding system, engines, and air blowers. However, there are challenging issues in a high speed motor technology: 1) robust mechanical structure, 2) materials like low loss silicon steel and high tensile strength, and 3) control issues such as the PWM delay, the PWM distortion, and the iron loss. Especially, the iron loss is usually neglected in the general permanent magnet synchronous motor (PMSM) control. Aside from the motor efficiency, the iron loss alters the PMSM dynamic model. Since the iron loss is not reflected in the conventional sensorless methods, the angle error grows steadily as the speed increases to an extremely high region. In this paper, a sensorless control method considering the iron loss is proposed. It cures the angle error in a high speed region, and the performances are demonstrated through simulation and experimental results.

This paper proposes a novel position sensorless control in the overmodulation range of an inverter for IPMSMs with magnetic non-linearity. This paper describes the simultaneous achievement of (1) position sensorless control, (2) robust maximum torque per ampere control in consideration of the magnetic nonlinearity in an IPMSM, and (3) robust overmodulation drives of the inverter. First, this paper describes the maximum torque control method based on a new mathematical model of an IPMSM. Next, this paper proposes a modification method for the voltage references. Finally, this paper shows the performances of the proposed method.
