Systems with variable frequency drives may experience torsional vibration. One reason is the pulsating nature of motor torque due to converter supply, another one is the electro-mechanical interaction and the effects of closed loop control. This paper deals with the speed control of elastic drive systems, mainly from torsional performance point of view. Modeling of elastic shaft string is being explored. The importance of control engineering to minimize the torsional vibration is explained. The… CONTINUE READING
