摘要：AbstractIn this contribution, a methodology from identification to sensorless control for a vibrating membrane pump prototype is presented and evaluated, with the objective to drive an innovative cardiac assist device. For this purpose, a model of the pump is presented to design an observer-based stroke controller that only uses current measurement. Model parameters are identified experimentally with a dedicated test bench and are used to tune the controller. The control strategy is evaluated on a hydraulic test bench.
