This paper describes the problem of design of an experimental setup for rotordynamic analysis and unbalance control. The rotor system has two disks in an asymmetrical configuration along a steel shaft which is connected to a three phase AC motor by a flexible coupling. A suspension with two linear electromechanical actuators is used to control actively the(More)
In this work a LQR scheme for vibration control in a rotor system is presented. The rotor system has two disks in an asymmetrical configuration along the shaft and its model is obtained by applying finite element techniques. A reduced order model of seven degrees of freedom is experimentally validated for the synthesis of active LQR control laws, using both(More)
This work deals with the problem of modelling and analysis in rotordynamics as well as the active control of vibrations caused by unbalance in a rotor system. The system model was obtained by Finite Element Method taking into account the gyroscopic effects. The finite element model is used to get the Campbell diagram, the critical speeds, the modal shapes(More)
In this paper the problem of modeling, analysis and unbalance response control of a rotor system with two disks in an asymmetrical configuration is treated. The Finite Element Method (FEM) is used to get the system model including the gyroscopic effects and then, the obtained model is experimentally validated. Rotordynamic analysis is carried out using the(More)
In this paper an algebraic technique for unbalance parameters identification along with an active control scheme for a rotor bearing system are presented. The system has two disks asymmetrically located along the shaft which is supported by a conventional ball bearing at one end and by an active suspension at the other one. The active suspension is based on(More)
This work treats the problem of vibration control in a rotor-bearing system using a passive absorber with controllable stiffness. The primary system consists in a rotor system mounted on two supports at its ends, one of them is a classical journal bearing and the other one is a bearing on a slider which can be displaced in order to change the distance(More)
