Field Oriented Control-Based Reduction of the Vibration and Power Consumption of a Blood Pump

Power quality and energy efficiency are of great importance in motor control. The motor of any medical device needs to have a smooth torque and minimal vibration in order to maximise its energy efficiency and patient comfort. Furthermore, in rotary blood pumps, excessive energy wasted due to vibration is converted into uncontrolled movement of the mechanical parts and thus could reduce the life of the motor-pump. Besides mechanical or hydraulic origin, one of the causes of vibration in any pump is torque ripple resulting from motor phase commutation. In this paper, using relevant equipment, two extreme scenarios were examined for vibration and electrical efficiency comparison due to power quality in a blood pump: one trapezoidal control with a trapezoidal phase current output; the other a field oriented control (FOC) with a non-distorted sinusoidal phase current. The test motor-pump was the Arteriovenous Fistula Eligibility (AFE) System that is used prior to haemodialysis. The trapezoidal technique was implemented utilising the Allegro a4941 fan driver (Allegro Microsystem, 2012), and the FOC technique was implemented using the Texas Instrument digital signal processor (TMS320F28335). The aim was to reduce the energy wasted over vibration, and to achieve smooth operation of the AFE System. Vibration was measured with a one-axis accelerometer; results showed considerably lower vibration due to less current ripple associated with the FOC control as well as lower power consumption.

This paper presents a model-based monitoring approach for the estimation of the elevator rail friction forces. This model-based monitoring approach is based on a Linear Parameter Varying (LPV) model of a 1:1 elevator installation, comprising both the mechanical and the electrical subsystems. The Extended Kalman algorithm (EKF) is then employed as an observer for the joint estimation of the elevator LPV states and parameters. Finally, the estimated rail friction forces are evaluated and energy efficiency indicators describing elevator performance during the ride are obtained.
