Calculation of parameters and accurate control with real-time compensator in drive system of pulsatile blood pump / 中国医疗器械杂志

ABSTRACT

This article introduces a new method using the servo motor which is controlled by ARM microcontroller to provide power for a pulsatile blood pump to beat. This method is featured with straightforward structure, accurate control, excellent timeliness, stable performance and small noise. And it can adjust the rate of beat, the rate of flow and the compression ratio according to actual demand.
