Open publisher page 0 citations

Abstract

The characteristics of nonlinearity of the suspension system in maglev train are analyzed.Starting from improvement of the anti-interference and loading capacity for the suspension system,a status feedback controller is designed by use of nonlinear H∞control theory.And a status observer is built so that the output feedback controller is realized.Simulation and test results show that the controller works efficiently for anti-interference of the suspension system for maglev train.
