本计划的目的是建立模型，模拟和实验验证所提出的无位置传感器的永磁同步电机变速驱动的启动和位置定位算法。取消位置传感器使电机封装紧凑，更便宜，机械坚固耐用，从而提高了其在所有情况下的运行可靠性。这些优点在机器人驱动、航空航天执行器、机床主轴驱动和许多国防应用中使用的电力驱动等应用中至关重要。无位置传感器永磁同步电机驱动器是理想的应用在家电，汽车和手工工具行业，因为他们的低成本。预计这项研究的结果将从位置传感器获得的位置信息中解放对永磁同步电机变速驱动器的控制，从而使该系统在高性能应用以及上述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.
