PhD Studentship: Electric Drives System of High Speed Permanent Magnet Motor Control

Introduction

This project aims to enhance the system performance of high-speed permanent magnet synchronous motors (PMSMs) drive which are critical in numerous applications including domestic appliances, aerospace, electric vehicles, and industrial automation, where high power rate and compact size are required. By increasing the motor speed, either boosting power output without altering motor size or maintaining the same power output while reducing motor dimensions is made possible.

Project details

The proposed project aims to address the existing challenges of high speed motor drive system, such as low position detection accuracy, low system stability, and large current harmonics. To achieve that, the project will involve extensive research, including a comprehensive analysis of various inverter/controller topologies and corresponding modulation strategies to determine the most suitable options for the target applications. Additionally, the project will address various motor control strategies to ensure optimal performance by increasing system efficiency and reliability while reducing system complexity.
The importance of this research lies in its potential to enhance the sensorless position detection accuracy, improve system stability, and suppress current harmonics for various applications. This project has the potential to significantly impact multiple industries, making it a critical area of research and development.

Funding

This is a fully-funded studentship, including tuition fees, stipend/bursary (£18,622 p/a) and additional allowances for training, conference attendance and fieldwork.

Benefits

The successful candidate will receive comprehensive research training including technical, personal and professional skills.

All researchers at Coventry University (from PhD to Professor) are part of the Doctoral College and Centre for Research Capability and Development, which provides support with high-quality training and career development activities.
