人工心脏是一种商业上很有趣的技术,它严重依赖于反馈控制,特别是使用磁力轴承的离心泵实现。本文探讨了这些泵的反馈控制的几个例子,包括位置传感的参数估计,基于观测器的电机换向,在高度不确定的流体动力作用下的刚性叶轮的位置控制,以及在极其复杂的对象上利用困难的测量来实现不确定目标(由于经验不足)的泵流量调节(生理控制)。这些问题是自动控制的生物医学应用范围不断扩大的典型问题。
Artificial hearts are a commercially interesting technology which relies heavily on feedback control, particularly with centrifugal pump implementations using magnetic bearings. Several examples of feedback control in these pumps were explored in this paper, including parameter estimation for position sensing, observer based motor commutation, position control of the rigid impeller subjected to highly uncertain fluid dynamic forces, and pump discharge rate regulation (physiological control) to achieve uncertain objectives (due to insufficient experience) using difficult measurements on an extremely complex plant. Such problems are typical of an expanding range of biomedical applications for automatic control.
