dc.description.abstract Permanent magnet synchronous machines (PMSM) are widely used due to their unique characteristics including high efficiency, high power density, simple construction, simple maintenance, and relative ease of control. With increasing need for automation, survivable and fault tolerant motor drives are highly in demand in many sectors of industry. Advancement in the area of modern power electronics has allowed researchers a great deal of flexibility in implementing complex control routines. While considerable of focus has been placed on improving schemes of control, not much effort has been put improvements in the performance of electric drives. It is also important to note that in some cases solving a problem has resulted in counter effects on other performance indices of the energy conversion device. This study investigates a new approach to solving these problems. It presents a design and analysis technique based on the required target specification for each system. Salient attributes of this approach include: Development of a systematic synthesis methodology for PMSM drives. Development of a new optimal control resulting in 75% reduction in torque pulsation of PMSM drive. Development of a control method for independent control of the tangential and normal components of the electromagnetic force. Quiet, vibration-free operation of an electric drive is a prime objective in naval and military applications. By manipulating the tangential and normal components of magnetic field in various parts of the machine, acoustic noise owing to radial and tangential vibrations have been mitigated. The method presented offers a new numerical technique for analysis and design of a PMSM. This technique is time- efficient and offers an insightful version of the magnetic field in the machine. It combines ideas from electromechanical energy conversion, signal reconstruction, pattern recognition, and power electronics to create novel solutions and paves the road for development of cost effective, highly efficient, survivable, and reliable electric motor drives. en_US
