摘要：
Methods, systems, and computer readable media for controlling ventricular assist devices are disclosed. In some embodiments, the method includes receiving at least one reference pump speed differential associated with a pump of a ventricular assist device； determining a filtered pump speed differential associated with the pump of a ventricular assist device； and adjusting, using a feedback based controller algorithm, current to the pump based on the at least one reference pump speed differential and the filtered pump speed differential. In some embodiments, the system includes a controller implemented using the non-transitory computer readable medium, wherein the controller is configured for receiving at least one reference pump speed differential associated with a pump of a ventricular assist device； determining a filtered pump speed differential associated with the pump of a ventricular assist device； and adjusting current to the pump based on the at least one reference pump speed differential and the filtered pump speed differential.
