中文摘要：

针对血泵对运动控制系统要求比较高的特点,介绍了外磁驱动式血泵控制系统的设计原理,采用反电动势过零法和磁定位启动的控制策略,采用TMS320LF2407设计无位置传感器无刷直流电动机控制系统,满足了外磁场驱动式血泵控制系统的使用要求。

英文摘要：

In view of the blood pump to the movement control system request quite high characteristic, elaborated in detail the extracorporeal magnetic field blood pump control system design principle, proposed uses control strategy which the counter electromotive force law and magnetism localization starts, utilizes TI Corporation movement control system special-purpose DSP TMS320LF2407 realization based on the non-position transducer extracorporeal magnetic field blood pump control system.
