Discussion on Robust Control Applied to Active Magnetic Bearing Rotor System

Adaptive Fuzzy Kalman Filter Applied for Identification of Rotor/active Magnetic Bearing Dynamics

The main goal of this research is to identify the system parameters of the dynamics of Rotor/Active Magnetic Bearing (Rotor/AMB) system employed in turbo molecular pumps (TMPs). The identification approach adopted in this work is based on experimental analysis and the application of Fuzzy Logic Adaptive ControlExtended Kalman Filter (FLAC-EKF). The estimation error for either system state or sy...

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...

The Development of a Flexible Rotor Active Magnetic Bearing System

A design process comprising aspects of modelling and analysis is developed, implemented and verified for a flexible rotor active magnetic bearing system. The system is specified to experience the first three critical frequencies up to an operating speed of 10,000 rpm. Rotor stability at critical frequencies places specific constraints on the equivalent stiffness and damping parameters of the ac...

Femlab Software Applied to Active Magnetic Bearing Analysis

In recent years a number of rotary machines with Active Magnetic Bearings have been designed in order to eliminate the lubricant medium, vibration and noise, and to achieve high velocities and loads. These systems are complicated due to the construction of mechanical, electrical and electronic circuits. A wide range analysis is required during the design procedure – from the construction stage ...
