Output Control of Three-Axis PMSG Wind Turbine Considering Torsional Vibration Using H Infinity Control

, 2020
Due to changes in wind, the torque obtained from the wind turbine always fluctuates. Here, the wind turbine and the rotor of the generator are connected by a shaft that is one elastic body, and each rotating body has different inertia.

Flutter and forced response of mistuned rotors using standing wave analysis [PDF]

, 1983
A standing wave approach is applied to the analysis of the flutter and forced response of tuned and mistuned rotors. The traditional traveling wave cascade airforces are recast into standing wave arbitrary motion form using Pade approximants, and the ...

Torsional Vibrations in a Crank Shaft [PDF]

, 1991
In this paper, we analyze the torsion in the crank shaft of a gas compressor with one crank. The effect of damping will not be studied here. The geometry is as drawn in Fig. 1. Two forces are exerted on the shaft. First, it is at one end driven by a motor.
