| 摘 要： | 基于传统S曲线控制算法,提出了一种能促进轴流式血泵升速过程驱动性能研究的三段S曲线升速控制方法.建立了S曲线升速模型,并离散求解得到定时常数和步数等参数;再利用上位机通信将参数实时传递给单片机,实现血泵升速过程S曲线控制.实验结果表明,血泵启动速度为300 r/m in,达到最大稳定转速为6 000 r/m in时,使得血泵运行快速而且驱动能力最大的S曲线的加速周期约为1.2 s.相对以往的血泵升速控制过程,驱动时间明显缩短,振动噪声小,加速性能良好.

| Abstract: | Based on the traditional S-curve control algorithm,a three-section Scurve speed-rising-control method which can promote drive performance of the blood pump was proposed.An S-curve acceleration model was established,and then time constant and steps were obtained by discrete solution.The parameters were passed to the microcontroller in real time by using PC communication,and eventually the S-curve control method was realized in the acceleration process.The results show that the blood pump can reach the fastes... |
