   Adaptive Friction Compensation of a Linear Voice Coil Servomotor
By Mohannad TAKROURI [View]
[Download]

Abstract: This paper presents an adaptive observer for friction identification and compensation in a linearservomotor. The objective is to compensate the dead-zone phenomenon caused by static and Coulombfriction and improve the tracking accuracy of the positioning system. Experimental results areprovided to confirm the effectiveness of the adaptive compensation scheme.

   Impact of the carrier phase shift on the low frequency harmonics of Medium Voltage drives
By Hamza EL JIHAD [View]
[Download]

Abstract: Usually in asynchronous Pulse Width Modulation (PWM) control strategy of medium voltage drives, the carrier and the target reference are asynchronous. In order to reduce the low frequency (LF) harmonic (less than H13), the carrier is synchronized with the target reference by fixing an integer N = Fpwm/Ftarget ratio. In addition, the influence of the phase position of the carrier within the target reference is studied. The theoretical and experimental results show that the magnitudes of these LF harmonics can be reduced by a ratio up to 12.

   Sensorless Position Estimation using a Search based Online Commissionable Method (SONIC)
By Kris SCICLUNA [View]
[Download]

Abstract: This paper presents an innovative method for the rotor position estimation of Surface Mounted Permanent Magnet Synchronous Machines at low/zero speed conditions. The proposed algorithm is based on an iterative search of position dependent saliency maps commissioned online. The method is also applicable to machines with non-ideal sinusoidal saliencies. Experimental results for saliency mapping at different injection angles in the stationary frame are presented. The performance of the observer at low and zero speed is also evaluated.

   Variable-speed-drive-based estimation of the pressure drop caused by filter fouling in fan systems
By Santeri PÖYHÖNEN [View]
[Download]

Abstract: Variable-speed drives (VSD) can be utilized in fluid handling system diagnosis and monitoring methods.Many of these methods can be implemented without additional sensors, which together with the ubiquityof VSDs makes them cost-efficient. This paper proposes a sensorless VSD-based method for estimatingthe pressure drop caused by air filter fouling.
