[Simulation of a regulation mechanism in inserting an artificial heart, by which the left and right pumps require the same output volume].

The problems of balance of the blood volume in the circulatory system are demonstrated in the application of an artificial heart by means of a mathematical function model of the human organism. The lung is endangered specially in case the right pump brings more than the left pumps away. Therefore a suitable controller was selected: it guarantees the equal output of the right and left pump. A PI-controller was used, because the complete abolition of the control deviation is more important than the dynamics. Variants were discussed about the arrangement of this controller in the total control of the artificial heart.
