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.

提出的职业规划的目标是开发一个强大的电力电子和电机驱动程序连接本科教育和研究生研究在阿克伦大学。拟建项目的大纲如下。一个研究项目和一个本科生特别项目将同时进行。开关磁阻电机（SRM）驱动的基本问题将在该计划的研究部分得到解决。一个用于SRM的转换器拓扑将通过由首席研究员和博士研究生指导的本科生研究来开发。拟议的研究项目将产生一名博士，两名硕士和一批专业的学士学位毕业生。该计划的教育部分建议从初级EE学生中选出一个NSF电力电子小组。由申请人（主要研究人员）和博士生指导小组。该小组将通过全面的电力电子和电机驱动计划进行指导。职业规划将启动电力电子和电机驱动领域的持续方案。今后，每年将选拔一组本科生和一名博士生，并选择一个合适的研究课题。该计划预计将在NSF项目完成后通过工业赞助继续进行。此外，PI还将组建一个由电气、机械和化学工程学院组成的小组，来监督有关电动/混合动力汽车的本科项目。所提出的研究的独特贡献是在SRM驱动器中同时实现间接位置传感控制的转矩脉动最小化，以及用于低压应用的新颖，高效，可再生的SRM转换器拓扑结构。所开发的间接位置传感方案将适用于所有类型的应用，并将涵盖广泛的速度范围，包括零速度。该方案是基于滑模观测器理论，转子位置将估计为一个状态变量，从终端测量电压和电流。滑模观测器具有对参数变化不敏感的优点。提出的转矩纹波最小化方案是基于电机相电流的最优电流分布。所建立的SRM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)转换器拓扑发展，（II）间接位置传感器发展，（III）扭矩脉动最小化，（IV）驱动集成。提出的职业规划将培养一批从电力电子和电机驱动的学士到博士水平的专业学生。这些学生在行业的培训时间将大大缩短。本科生大量接触研究环境将吸引更多的美国学生攻读研究生课程。不与任何工业发展项目挂钩的基础研究可以通过这一拟议计划实现。这项研究将使汽车、航空航天和消费品行业受益。
