Blood pump systems including a continuous flow blood pump and methods for controlling a continuous flow blood pump operate the blood pump to simulate target pressure-flow characteristics that are different from native pressure-flow characteristics of the blood pump. A method for controlling a continuous flow blood pump driven by a motor includes operating the motor at a first rotational rate. A first flow rate of the continuous flow blood pump driven at the first rotational rate is measured and/or estimated. The first flow rate is used to determine a second rotational rate based on target pump characteristic data corresponding to target pressure-flow characteristics for the continuous flow blood pump different from pressure-flow characteristics of the continuous flow blood pump when driven by the motor at a constant rotational speed. The second rotational rate is different from the first rotational rate. The motor is then operated at the second rotational rate.
