INT 9820434LipoThis U.S.-Czech engineering research project between Thomas Lipo of the University of Wisconsin, Madison, and Miroslav Chomat of the Czech Institute of Electrical Engineering, Prague, features development of a theoretical basis for the analysis, modeling, and control of variable-speed drives that employ advanced types of low cost, highly efficient electric machines. The researchers intend to derive detailed mathematical models suitable for simulating both transient and steady state operations for such drives. Their models in turn will permit analysis of electromagnetic processes taking place in the machines under various operating conditions.Results should shed light on the dynamic behavior of the drives and improve our understanding of spatial distribution of the magnetic field in electric machines, including the influence of magnetic saturation, iron losses, and higher space harmonics. Experimental investigations are also planned to verify the mathematical models and optimize the control algorithms used. Basic findings may yield new circuit and control concepts for reduced cost variable speed drives with significant potential for application in low cost air conditioning drives.This electrical engineering research project fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.

麦迪逊威斯康星大学的Thomas Lipo和布拉格捷克电气工程研究所的Miroslav Chomat共同开展了一个美国-捷克工程研究项目，该项目为采用先进类型的低成本、高效电机的变速驱动器的分析、建模和控制提供了理论基础。研究人员打算推导出适合于模拟这种驱动器的瞬态和稳态操作的详细数学模型。他们的模型反过来将允许分析在各种操作条件下发生在机器中的电磁过程。结果将揭示驱动器的动态行为，并提高我们对电机磁场空间分布的理解，包括磁饱和、铁损耗和高空间谐波的影响。实验研究也计划验证数学模型和优化所使用的控制算法。基本发现可能产生新的电路和控制概念，以降低成本的变速驱动器具有显著的潜力应用在低成本的空调驱动。该电气工程研究项目通过使美国和中欧的专家能够在共同感兴趣和能力强的领域结合互补的人才和共享研究资源，实现了推进科学知识的计划目标。
