摘要：
Fuzzy logic regulation of flow was investigated in simulation of a model of the Cleveland Clinic Foundation rotodynamic Cardio Pulmonary Bypass blood pump comprised of impeller model #4079 and volute model #4080. A non-linear model of the pump was derived from pump maps obtained from measurements using a custom made pump dynamometer. Pump speed and generated delta pressure were used as inputs to a fuzzy engine in charge of manipulating the pump's speed; the fuzzy controller was capable of maintaining a setpoint of 6 +/- 0.5 l/min when presented with pressure disturbances over a range of +/- 50 mmHg from the baseline of 100 mmHg.
