CAREER: Power Electronics and Motor Drives Technology Enhancement Through Education and Research

ECS-9702370侯赛因拟议的职业计划的目标是开发一个强大的电力电子和电机驱动课程，将阿克伦大学的本科教育与研究生研究联系起来。拟议项目的提纲如下。一个研究项目和一个本科生特别项目将同时进行。该计划的研究部分将解决开关磁阻电机(SRM)驱动的基本问题。在首席研究员和一名博士研究生的指导下，将通过本科生的研究开发出开关磁阻电机的变流器拓扑。拟议的研究项目将产生一名博士、两名硕士和一批专业的理科学士毕业生。该计划的教育部分建议通过从低年级的EE学生中选拔来组建NSF电力电子集团。申请人(首席调查员)和博士生将监督小组。该小组将通过一个全面的电力电子和电机驱动计划进行指导。职业生涯计划将启动电力电子和电机驱动领域的持续计划。今后，每年将选出一批本科生和一名博士生，并选择合适的研究课题。预计在NSF项目完成后，该计划将通过行业赞助继续进行。此外，PI将汇集一批来自电气、机械和化学工程的学院，以指导电动/混合动力汽车的本科生项目。所提出的研究的独特贡献是在开关磁阻电机驱动中同时实现转矩脉动最小化和间接位置检测控制，以及一种适用于低电压应用的新型、高效、可再生的开关磁阻电机变流器拓扑。即将开发的间接位置检测方案将适用于所有类型的应用，并将涵盖包括零速度在内的广泛速度范围。该方案基于滑模观测器理论，仅根据电压和电流的终端测量来估计转子位置作为状态变量。滑模观测器具有对参数变化不敏感的优点。提出的转矩脉动最小化方案是基于电机相电流的最优电流分布。所开发的开关磁阻电机模型将考虑磁饱和的影响。拟议研究的工作时间表分为四个阶段：(1)变流器拓扑开发，(Ii)间接位置传感器开发，(Iii)力矩脉动最小化，和(Iv)驱动器集成。拟议的职业计划将培养一批专业学生，从电力电子和电机驱动的学士到博士水平。这些学生在行业中的培训期将大幅缩短。本科生在研究环境中的大量接触将吸引更多的美国学生进入研究生课程。通过这项拟议的计划，可以进行基础研究，而不是与任何工业发展项目挂钩。这项研究将有益于汽车、航空航天和消费品行业。

ECS-9702370 Husain The objective of the proposed career plan is to develop a strong power electronics and motor drives program linking undergraduate education with graduate research at The University of Akron. The outline of the proposed project is as follows. A research project and an undergraduate special program will proceed concurrently. Fundamental problems in switched reluctance motor (SRM) drives will be addressed in the research portion of the plan. A converter topology for SRM will be developed through undergraduate research guided by the principal investigator and a Ph.D. graduate student. The proposed research project will generate one Ph.D., two MS, and a group of specialized BS graduates. The education portion of the plan proposes to form an NSF Power Electronics Group through selection from junior level EE students. The applicant (principal investigatmr) and the Ph.D. student will supervise the group. The group will be guided through a comprehensive power electronics and motor drives program. The career plan will initiate a continuing program in the area of power electronics and motor drives. In the future, a group of undergraduate students and a Ph.D. student will be selected every year along with a suitable research topic. The plan is expected to be continued through industrial sponsorship after the completion of the NSF project. In addition, the PI will assemble a group of faculties from electrical, mechanical and chemical engineering to supervise undergraduate projects on electric/hybrid vehicles. The unique contribution of the proposed research is torque ripple minimization simultaneous with indirect position sensing control in SRM drives, and a novel, efficient, regenerative SRM converter topology for low-voltage applications. The indirect position sensing scheme to be developed will be suitable for all types of applications and will cover a wide speed range including zero speed. The scheme is based on sliding mode observer theory where the rotor po sition will be estimated as a state variable from terminal measurements of voltage and current only. The sliding mode observer has the advantage of insensitivity to parameter variation. The torque ripple minimization scheme proposed is based on optimal current profiling of the motor phase currents. The developed SRM model will consider the effects of magnetic saturation. The working schedule of the proposed research has been divided into four phases; (1) converter topology development,(II) indirect position sensor development, (III) torque ripple minimization, and (IV) integration of the drive. The proposed career plan will generate a group of specialized students from bachelors through doctoral level in power electronics and motor drives. The training period for these students in industries will be reduced significantly. Significant exposure of undergraduates to the research environment will attract more US students towards the graduate program. Fundamental research, not linked to any industrial development project, is possible through this proposed plan. The research will benedit the automotive, aerospace and consumer product industries.
