Constrained Control Design for Magnetic Bearing Systems
We study control problems in magnetic bearing systems that are subject to both input and state constraints. Apart from the usual restrictions on voltages and currents in the circuit systems, most magnetic bearing systems are subject to a severe state constraint: the motion of the rotor (the suspended object) is only allowed in an extremely small airgap, otherwise the collision of the rotor and ...
متن کاملOptimization-Based Multivariable Control System Design Package*
This paper describes an interactive, optimization-based multivariable control system design package which is currently under development at the University of California, Berkeley. The package will combine a number of subroutines from the Imperial College Multivariable Design System and the Kingston Polytechnic SLICE library with DELIGHT, the University of California, Berkeley, general purpose, ...
متن کاملNonlinear control for a large air-gap magnetic bearing system
Active magnetic bearings are increasingly being utilized in rotating machinery applications as an alternative to the conventional rolling-element and fluid-film bearing types. In this paper three control schemes for a large air-gap magnetic bearing system are described. In the large air-gap situation, the magnetic bearing system operates in highly nonlinear regimes .The non-linearity in this sy...
متن کاملContinuous Time Model Predictive Control for a Magnetic Bearing System
Abstract— The nature of active magnetic bearings has many advantages over the conventional bearing, as its operation is energy efficient and potentially leads to cleaner and noise-free environment. However, the successful operation of an active magnetic bearing system requires a complex real-time control system, because of its unstable characteristics, as well as its nature of being a multi-inp...
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...
