The conventional maximum torque per ampere (MTPA) operation usually neglects the derivative terms of interior permanent magnet synchronous motor (IPMSM) parameters, which significantly influences MTPA control accuracy. In this study, an scheme that considers is developed, and a parameter identification strategy inverter to be non-ideal developed for calculation IPMSM parameters terms. addition,...

For an interior permanent magnet synchronous motor (IPMSM) control system, the actual maximum torque per ampere (MTPA) trajectory may deviate from the ideal one with parameter variances, and thus the system may not obtain the maximum torque output. In view of this problem, a novel parameter identification method based on the model reference adaptive system (MRAS) is proposed in this paper. In t...

The algorithmic structure of a vector controller capable of high quality speed control of a synchronous reluctance motor with and without the use of a rotor position sensor is presented in this paper. The controller is based on a conventional saturated machine d-q model. Its main merit is that it can be operated in a sensorless control mode by executing a new, very accurate parameter dependent ...

This study investigates the influence of buried magnet arrangement on efficiency and drivability performance provided by an on-board interior permanent synchronous machine for a four-wheel-drive electric car with two single-speed powertrains. The relevant motor characteristics, including flux-linkage, inductance, electromagnetic torque, iron loss, total efficiency, are analyzed set six configur...

This paper presents a new method to optimize, from working cycle defined by torque and speed profiles, both the design control strategy of permanent magnet synchronous generators (PMSGs). The case 10 MW direct-drive generator for an Offshore wind turbine was chosen illustrate this method, which is based on d–q axis equivalent circuit model. It allows with reduced computation time, design, consi...

The purpose of the paper is to present the potentialities in terms of the control of a new kind of PM synchronous machine. With five phases and electromotive forces whose first (E1) and third (E3) harmonics are of similar amplitude, the studied machine, so-called bi-harmonic, has properties that are interesting for traction machine payload. With three-phase machines, supplied by a mono-harmonic...
