Fuzzy Logic Control of a Cardio Pulmonary Bypass Rotary Blood Pump

Centrifugal pumps, modeling, simulation, and fuzzy logic control.


This paper presents the results of fuzzy logic based flow regulation of a simulated model of a rotodynamic Cardio Pulmonary Bypass blood pump. A fuzzy logic controller was designed based on a system characterization obtained via off-line experimental data. The results from the tests revealed that the fuzzy controller is well suited to this application in which traditional control strategies may not perform well. The methodology developed for designing a fuzzy controller can be applied to any centrifugal pump where flow regulation is desired regardless of pump head disturbances.
