Inductive Displacement Sensors with a Notch Filter for an Active Magnetic Bearing System
Active magnetic bearing (AMB) systems support rotating shafts without any physical contact, using electromagnetic forces. Each radial AMB uses two pairs of electromagnets at opposite sides of the rotor. This allows the rotor to float in the air gap, and the machine to operate without frictional losses. In active magnetic suspension, displacement sensors are necessary to detect the radial and ax...
متن کاملModelling of Control System for an Active Magnetic Bearing
Active Magnetic Bearing (AMB) supports a rotor by magnetic attractive forces, without any mechanical contact. The paper presents a field-circuit model of an active magnetic bearing including its control loop. The basic parameters of the active magnetic system has been obtained from a FEM analysis of an magnetic bearing actuator. The position control system is based on operation of the local con...
متن کاملDeterministic Models of an Active Magnetic Bearing System
In this paper the development of mathematical model of voltage-input and current-input active magnetic bearing (AMB) system in deterministic form is presented. The AMB system, which is open-loop unstable and highly coupled due to nonlinearities inherited in the system such as gyroscopic effect and mass imbalance, requires a dynamic controller that can stabilize the system. In order to synthesiz...
متن کاملA Disturbance Compensation Control for an Active Magnetic Bearing System by a Multiple FXLMS Algorithm
In this paper, a design technique is proposed for a disturbance feedforward compensation control to attenuate disturbance responses in an active magnetic bearing system, which is subject to base motion. To eliminate the sensitivity of model accuracy to disturbance responses, the proposed design technique is an experimental feedforward compensator, developed from an adaptive estimation, by means...
متن کاملAnalysis of Vibration Characteristics of PD Control Active Magnetic Bearing and Cracked Rotor System (RESEARCH NOTE)
Crack fault of rotor is one of the most prominent problems faced by magnetic bearing rotor system. In order to improve the safety performance of this kind of machinery, it is necessary to research the vibration characteristics of magnetic bearing cracked rotor system. In this paper, the stiffness model of the crack shaft element was established by the strain energy release rate (SERR) theory. T...
