Resonant inductive displacement sensor for active magnetic bearings
Sensors and Actuators A: Physical, 2019Abstract This paper presents a resonant inductive sensor for radial displacement in Active Magnetic Bearing (AMB) systems. The device consists of a wire coil wound around a tooth of a conventional eight-pole radial actuator of the bearing. The proposed device is different from standard inductive sensor schemes since the sensing coil is excited by the

NASH STRATEGY APPLIED TO ACTIVE MAGNETIC BEARING CONTROL
IFAC Proceedings Volumes, 2005In this paper, Nash strategy is applied for controlling an active magnetic bearing. Different criteria are associated to each input of the dynamical system. The Nash controls are associated with Coupled Algebraic Riccati Equations. A state feedback from Nash strategy is designed based on a linearized system. A comparison of Nash and LQ control, applied

Isotropic Optimal Control of Active Magnetic Bearing System
Journal of Dynamic Systems, Measurement, and Control, 1996As a new rotor control scheme, isotropic control of weakly anisotropic rotor bearing system in complex state space is proposed, which utilizes the concepts on the eigenstructure of the isotropic rotor system. Advantages of the scheme are that the controlled system always retains isotropic eigenstructure, leading to circular whirling due to unbalance ...

Losses estimation and modelling in active magnetic bearings
2014 16th European Conference on Power Electronics and Applications, 2014Active magnetic bearings (AMBs) are becoming very popular in high speed electrical machines applications in the last decade. As the interest in them grows the necessity to optimise all the aspects of their operation arises. This paper presents the analytical way of calculating losses of active magnetic bearings based on reluctance network method.

Active magnetic bearing requirements for turbomachinery
IEE Colloquium on High Speed Bearings for Electrical Machines, 1997Rolls Royce (RR) have been interested in the application of active magnetic bearings (AMBs) for a number of years and have carried out two demonstrator programmes and a number of design studies. The generic benefits of AMBs to a range of machinery are summarised. The authors discuss the technology demonstrators, the design requirements, robust control,
