Title:

Fuzzy Control of a Brushless DC Motor for an Artificial Heart

Speaker:
Dr. Nejila Parspour
Institute for Electronic Machines

Abstract:

This talk presents a fuzzy controlled brushless DC motor deployed in a
left
ventricular heart assist system. The medical system consists of a
bloodpump,
a centrifugal pump, a brushless DC motor, a solenoid, power supply and
controls. The brushless DC motor operates sensorless and is developed
with
respect to the special requirements of an implantable heart assist
device. A
fuzzy logic controller is used to control the ventricular blood pressure
and
the blood volume flow (cardiac output). This approach enables the
designer
to describe process situations with human words in a very transparent
way
and to make control decision, based on linguistic rules. These rules can
be
generated or changed by the medical doctor for the individual
application.
