Feedback Linearization of a Blower in an Anesthesia Workstation

Abstract Radial compressors, Blowers, which are often used in modern devices for medical ventilation, known to have non-linear dynamics regarding the generated pressure. To make them accessible large field of linear control theory their model needs be linearized. This paper uses a gray box blower driven by brushless direct current (BLDC) motor design controller based on feedback linearization. The is designed achieve approximate closed loop behavior system. then evaluated concerning reference tracking and disturbance rejection simulation demonstrator evaluation showed that an was achieved.
