Development of power apparatus and advanced motor drive systems

全球变暖和气候变化的主要原因之一是与火力发电相关的温室气体的产生。超过60%的电力是由电机消耗的。多年来，申请人一直在开发高效率的内部永磁（IPM）电机技术，这可能有助于对抗全球变暖。在过去的5年资助期内，申请人专注于解决标准线路启动IPM电机的基本设计问题。获得博士学位4人，硕士学位5人，博士后5人，发表期刊论文33篇，会议论文45篇，专利2项，字母组合论文3篇。这些已发表的成果引起了相当大的工业兴趣和国际合作。由于他的努力，申请人获得了四项主要的IEEE奖，这表明他的工作被同行和行业认为是非常重要的。然而，对速度的快速和精确控制的需求正引领着先进的新型电动机驱动系统的发展。因此，未来5年的研究目标是：a)开发具有高速高性能的内部永磁（IPM）电机，(b)使用智能控制器设计和构建高速无轴承电机驱动，c)利用新的小波调制技术测试功率逆变器的创新技术。这些目标将在软件和硬件开发中实现。将建立和测试实验室原型。2008-2013年将招收本科生4人、硕士生5人、博士生4人、博士后5人。科学的方法将包括详细的分析和开发无轴承电机和相关的电力电子系统模型，包括控制接口。高性能和高效的运动控制技术将主导包括加拿大在内的全球特定应用市场。未来5年，加拿大在先进电机和电力电子系统方面的研究课题对经济开发具有重要意义。为实现拟议研究的目标，要求每年提供7万美元的五年赠款。

One of the major causes of global warming and climate change is the production of green house gas associated with thermal power generation. Over 60% of generated electric power is consumed by motors. For many years, the applicant has been developing high efficiency interior permanent magnet (IPM) motor technology, which could help in the fight to counteract global warming. Over the previous 5-year grant period, the applicant focused on solving the basic design issues of standard line start IPM motors. This resulted in 4 PhD and 5 M.Eng graduates, 5 post-doctoral fellows, 33 Journal and 45 conference papers, 2 patents, 3 monograms. These published results have aroused considerable industrial interests and international collaborations. For his efforts, the applicant has received four major IEEE Awards, which indicates that his work is considered very significant by his peers and by industry. However, the demand of fast and precision control of speed is spearheading the development of advanced new electric motor drive systems. Thus, the objectives of the proposed research for the coming 5 years are: a) Development of interior permanent magnet (IPM) motors having high performances at super speeds, (b) Design and build high speed bearingless motor drive using intelligent controllers, c) Test innovative new technology for power inverters utilizing new wavelet modulation techniques. These objectives will be achieved in both software and hardware developments. Laboratory prototypes will be built and tested. These will be realized with the help of 4 undergraduate, 5 M.Eng and 4 PhD students and 5 post doctoral fellows in 2008-2013. The scientific approaches will involve detailed analysis and development of system models of the bearingless motors and associated power electronics including control interfaces. High performance and efficient motion control technology will dominate the specific applications market worldwide including Canada. The topics of the proposed research on advanced electric machines and power electronics system in the next 5 years are significant for economic exploitations in Canada. A five-year grant of $70,000 per year is requested to achieve the objectives of the propsed research.
