摘要：

For a novel blood pressure measurement system, we design a cascaded controller that consists of two classic feedback loops and an iterative learning algorithm. We show that the bandwidth of the feedback loops is limited by the measurement noise of the ultrasound sensor and that this restriction can be circumvented by exploiting the repetitive nature of the disturbance that is induced by the oscillating arterial pressure.
