“…There are three major initial position detection methods based on DC-link current or terminal voltage measurement used to identify the rotor position [23][24][25][26][27]. These methods include the rise time measurement of DC-link current, terminal voltage pulse width detection, and peak current measurement of DC-link current.…”

“…These challenges are primarily from transformer core saturation and resistive voltage drops within the system due to the presence of sinewave filters, transformers, and long cables. Also, when the rotor's initial position is unknown at a standstill, the motor may experience temporary reverse rotation and result in decreased starting torque [22][23][24][25][26][27]. Moreover, if the initial rotor position has significant deviation and the rotor is not aligned with the applied frequency, the motor may lose synchronism [24,25].…”

Permanent magnet (PM) motors are gaining prominence in subsea applications such as drilling, pumping, and boosting for oil and natural gas extraction. These motors are gradually replacing traditional induction motors. However, starting and operating PM motors at low speeds under heavy loads poses significant challenges. This is because of unknown initial rotor positions and resistive voltage drops due to the presence of a sinewave filter, transformer, and long cable. An unknown rotor position may result in temporary reverse speed, which may cause a loss of synchronism; therefore, initial rotor position estimation is preferable. Additionally, addressing the voltage drop issue requires careful voltage compensation to avoid transformer core saturation. In this paper, an enhanced V/Hz starting of a PM motor is proposed with initial position detection (IPD) and voltage compensation to start the motor reliably with a heavy load. The proposed control method is verified with controller hardware in the loop (C-HIL) real-time simulation using a Typhoon HIL-604 emulator and a Texas Instruments TMS320F28335 digital signal processor (DSP) control card.

“…The difference in outputs between these two models is employed to drive an appropriate adaptation mechanism, which in turn yields an estimated rotor speed. A comprehensive MRAS sensorless control system design technique in discrete-time domain for high-speed drives is proposed and discussed in [33,34].…”

Sensorless Control of Dual Three-Phase Permanent Magnet Synchronous Machines—A Review

et al. 2023

View full text Add to dashboard Cite

This paper presents an overview of various sensorless control methods, with a focus on dual three-phase permanent magnet synchronous machines (DTP-PMSM). Owing to the important role that DTP-PMSMs play in motion-control applications in industry, most academic researchers and industry activists seek to reduce costs and size while increasing the capability and efficiency of motion applications. This has led to an increase in the number of publications about multiphase machines in recent years. The purpose of this article is to review the most important sensorless control techniques, which are divided into two main categories, namely saliency-based control method for low-speed range and model-based control method for high-speed range. Both methods are subdivided into other categories, with a focus on DTP-PMSMs. The methods are compared with each other for the purpose of selecting the most suitable control technique for implementation in applications such as ship propulsion, wind turbines, and aerospace.
