摘　　要：介绍了一种用于人工心脏轴流式血泵无位置传感器永磁无刷直流电机闭环调速控制系统的设计,该设计利用自起动方式实现电机起动,当电机达到额定转速时,进入闭环控制系统,利用反电势逻辑积分法,实现无刷直流电机无位置传感器控制。The paper introduces a kind of closed loop timing control system, based on position-sensorless control of brushless DC motors, used in an axial blood pump of artificial heart. The design makes the motor start with a self-start mode. While the motor attains the rated speed it enters into the closed - loop control status. The control of the brushless DC motor without position-sensorless control is realized by employing the back-EMF logic integral method.
