Analysis 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...
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 کاملInductive 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...

Acknowledgments My special thank goes to my advisor Dr. Marcio S. de Queiroz. I thank him for all his continued support in all stages of this project. I would also like to extend my sincere gratitude to my committee members Dr. Kemin Zhou and Dr. Yitshak Ram for their valuable support and guidance. Abstract A solution to the problem of AMB control with reduced electrical power losses will be pr...
متن کاملAdaptive control of an active magnetic bearing with external disturbance.
Adaptive back stepping control (ABC) is originally applied to a linearized model of an active magnetic bearing (AMB) system. Our control goal is to regulate the deviation of the magnetic bearing from its equilibrium position in the presence of an external disturbance and system uncertainties. Two types of ABC methods are developed on the AMB system. One is based on full state feedback, for whic...
