Abstract

A computer simulation of the Penn State electric total artificial heart (TAH) and mock circulatory system has been developed. The purpose of the simulation is to develop digital control strategies for the TAH that give desired pusher plate velocity control and pump output regulation. To achieve the latter, an observer was used to predict pump output load pressures and inlet filling pressures. Simulation results show good observer prediction of the peak output pressure for a range of beatrates (60-90 bpm). Changes in mock loop parameters cause acceptable error in the observed outlet pressure ( greater than 10%). From the simulation, inlet pressures cannot be observed accurately enough to follow changes in system conditions.
