Pulsatile pressure/flow wave forms reproduction of blood in mechanical circulatory systems are still an open topic. Regarding the periodic behavior of pulsatile hemodynamics, a repetitive control algorithm was adopted as a potential methodology for rotary blood pumps. The developed algorithm was tested on a mock system including an oxygenator, a resistance, and a compliance. The post-oxygenator pressure served as the feedback of the control system. Initially, a model of the whole system was developed in order to use repetitive control algorithm. Then the performance of the developed algorithm was evaluated in three different scenarios. The experimental results indicated that the proposed method was able to accurately reproduce any pattern of pulsatile pressure. Moreover, it demonstrated an acceptable robustness in terms of model uncertainty and nonlinearity.
