Control of flexible rotor systems with active magnetic bearings
An approach is presented for the analysis and design of magnetic suspension systems with large flexible rotordynamics models including dynamics, control, and simulation. The objective is to formulate and synthesize a large-order, flexible shaft rotordynamics model for a flywheel supported with magnetic bearings. A finite element model of the rotor system is assembled and then employed to develo...
متن کاملExperiments in the Control of Unbalance Response Using Magnetic Bearings
Unbalance response is a common vibration problem associated with rotating machinery. For several years, researchers have demonstrated that this vibration could be greatly alleviated for machines using active magnetic bearings through active control. Many of the control strategies employed fall into a class which the authors have termed adaptive open loop control. In this paper, three algorithms...
متن کاملH∞ Robust Controller Design and Experimental Analysis of Active Magnetic Bearings with Flexible Rotor System
H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...
متن کاملRotor compliance minimization via μ-control of active magnetic bearings
Many important problems in the control of rotating machinery with active magnetic bearings (AMBs) concern the minimization of the dynamic compliance of the rotor at a single or several shaft locations which typically do not correspond to those of a sensor or actuator. Experimental results are presented which demonstrate that controller design problems of this type can be successfully handled vi...
