Modeling and experimental verification of a flexible rotor/AMB system

Abstract: Purpose -In this paper, the aim is to present a modeling strategy for a flexible rotor/active magnetic bearing (AMB) system with non-collocation. Special attention is paid to the vibration reduction and the stable passage through the first critical speed. Design/methodology/approach -The finite element method based on Euller-Bernoulli beam theory is applied in the formulation of the rotor model. Since rotor/AMB systems are complex mechatronic systems, reduced order approach is used in the control system design… Show more

“…The minor existing differences were compensated in order to obtain a more accurate numerical model. More details can be found in[15]. Finally, using this open loop model the closed loop model of the entire system (including notch filters and controllers) was built in Simulink.…”

“…For some types of drives, the finite stiffness of the mechanical connections can become apparent, resulting in undesirable electromagnetic variable vibrations. These include, but are not limited to, rolling mill drives, paper mill drives or robot drives [2][3][4][5]. The mentioned issue can also arise as a result of modifications to already operational drives, for example, the addition of magnetic couplings [6].…”

“…The problem of the non-stiff shaft was first considered in high-power applications, such as rolling mills, trains, conveyer or paper-machine drives (Valenzuela et al , 2005; Wang et al , 2006). With the development of inverter-feed drives, which significantly increase the dynamics of electromagnetic torque control, torsional vibrations appear, for example, in servo-drives, robot-arm-drives, wind-mill generation systems and others (Brogliato et al , 1995; Štimac et al , 2013; Molinas et al , 2010; Montague et al , 2012).…”
