摘　　要：针对外磁场驱动轴流式血泵的控制,提出基于心室功的控制算法。分析自然心脏和人工心脏之间做功关系,建立用于驱动血泵电机的控制模型,根据常态生理参数,对血泵的控制模型进行计算和实验。基于心室功的控制算法与其他控制算法比较,有利于评价左心室辅助装置的性能,更符合实际生理需求;充分发挥驱动电机效率,避免系统长期工作在高速阶段,从而避免系统高温,有助于抑制血泵对血液的破坏。The control arithmetic is proposed for axial blood pump driven by extracorporeal alternating magnet field based on ventricular work. According to health physiological parameters, the control model is verified by calculation and experiment. The control model used for driving blood pump is derived from the relationship of natural heart and artificial heart. By comparison with others, the control arithmetic based on ventricular work is more helpful in appraising the property of left ventricular aided device （LVAD）, in meeting human body＇s natural need, and in effective use of motor for avoiding motor running at high speed and hence preventing the blood from the destruction caused by a blood pump at high temperature.
