Model-Based Control of Pneumatically Driven Ventricular Assist Devices

摘要

The paper presents new approaches for the control of an extracorporeal ventricular assist device. It is based on a cascaded control of two subsystems. In the first subsystem a non-linear mode-based control approach was applied. In the outer loop, the control is based on a model prediction of the controlled variable, since no measurements are available. The proposed control of the pump volume adapts to time-variant, not directly measurable patient parameters.
