A Practical Solution for Torsional Vibrations Evasion in Variable Speed Drives

Abstract: The paper presents a practical solution for an existing drive-train to avoid torsional vibrations for variable speed drives under SPWM modulation technique. Torsional natural frequencies can be a problem because either ill defined in design stage or one of the mechanical parameters has changed after the initial design stage. The proposed method comprises of dividing the frequency range into several partitions where in each partition a value of modulation frequency ratio m f is chosen. A criterion is developed … Show more

“…L. Peng [6] used high elastic rubber coupling to suppress the torsional vibration of fan, while [1][2] described the coupling failure with higher rigidity after replacement. K. Nagata et al [7] and K. Elshawarby et al [8] improved the pulse width modulation (PWM) method of frequency converter to suppress the torsional vibration. R. Muszynski and J. Deskur [9] designed a proportional-integral-derivative (PID) controller to control the speed of frequency converter for suppressing the torsional vibration.…”
