Abstract :
In order to make an air-driven total artificial heart (TAR) implantable, the optimal operating point control method has been applied to the TAH controller. Because this method needs only the outflow rate of blood to regulate the stroke volume, it is not necessary to visually monitor the state of the sac in the implanted blood pump. Animal experiments have been carried out to evaluate the proposed controller by using an adult goat walking on a treadmill
