Research Initiation: Sensor-less Operation of Permanent Magnet Synchronous Motor Drives for Variable Speed Applica- tions in Robotics, Aerospace Actuators and Spindle Drives

本项目的目标是对所提出的无位置传感器永磁同步电机变速传动的启动和位置定位算法进行建模、仿真和实验验证。取消位置传感器使电机包装紧凑、成本更低、机械坚固耐用，从而提高了其在任何情况下的运行可靠性。这些优势在机器人驱动器、航空航天执行器、机床主轴驱动器和许多国防应用中使用的电子驱动器等应用中至关重要。无位置传感器永磁同步电机驱动器由于其低成本，非常适合用于家电、汽车和手动工具行业。预计这项研究的结果将使永磁同步电机变速驱动器的控制从位置传感器获得的位置信息中解放出来，从而使该系统能够在上述高性能应用和对成本敏感的低性能应用中大规模使用。

The objectives of this project are to model, simulate and experimentally verify the proposed starting and position orientation algorithms for permanent magnet synchronous motor variable speed drive without a position sensor. Doing away with the position sensor makes the motor packaging compact, less expensive and mechanically rugged and robust thus increasing its reliability of operation under all circumstances. These advantages are critical in applications such as robotic drives, aerospace actuators, machine tool spindle drives and electric drives used in many defense applications. Position sensor- less permanent magnet synchronous motor drives are ideal for use in appliance, automotive and hand-tool industries because of their low cost. It is anticipated that the results of this research would free the control of permanent magnet synchronous motor variable speed drives from position information obtained from the position sensors thus making the system open to large scale use in high performance applications as well as cost sensitive low performance applications described above.
