This paper presents a novel mock circulation for the evaluation of ventricular assist devices (VADs), which is based on a hardware-in-the-loop concept. A numerical model of the human blood circulation runs in real time and computes instantaneous pressure, volume, and flow rate values. The VAD to be tested is connected to a numerical-hydraulic interface,(More)
This paper discusses the application of a model-based feedback control loop for the air-to-fuel (AF) ratio instead of the standard exhaust gas recirculation (EGR) control loop that utilizes the hot-film air-mass meter (HFM) as control variable. A comparison between the model-based controller that contains information about the plant dynamics and the(More)
