This paper addresses the development and testing of an optimal position feedback controller for the Penn State electric ventricular-assist device (EVAD). The control law is designed to minimize the expected value of the EVAD's power consumption for a targeted patient population. The closed-loop control law is implemented on an Intel 8096 microprocessor and in vitro test runs show that this controller improves the EVAD's efficiency by 15-21%, when compared with the performance of the currently used feedforward control scheme.
本文论述了针对宾夕法尼亚州立大学电动心室辅助装置(EVAD)的最优位置反馈控制器的开发与测试。该控制律旨在将目标患者群体的EVAD功耗期望值降至最低。闭环控制律在英特尔8096微处理器上实现,体外测试运行表明,与目前使用的前馈控制方案的性能相比,该控制器可将EVAD的效率提高15% - 21%。
