Abstract
This paper leads with the problem of active balancing control on a rotor-bearing system. It is considered that one of the bearings can be automatically moved to control the effective rotor length and, as an immediate consequence, the rotor stiffness. Therefore, the rotor stiffness is considered as a control input of the system. An adaptive-like control scheme is proposed to reduce and stabilize the amplitude response of the system while it passes through of its first critical speed. Because the controller requires information of the eccentricity, an algebraic identification scheme is used for the on-line estimation of the eccentricity of the disk. Some numerical simulations are included to illustrate the unbalance compensation properties when the rotor is started and operated over the first critical speed.
