posted on 2012-01-10, 14:00 authored by Jun Yang, Argyrios C. Zolotas, Wen-Hua ChenWen-Hua Chen, Konstantinos Michail, Shihua LiThis paper investigates the disturbance rejection
problem of nonlinear MAGnetic LEViation (MAGLEV) suspension
system with “mismatching” disturbances. Here “mismatching”
refers to the disturbances that enter the system via different
channel to the control input. The disturbance referring in
this paper is mainly on load variation and unmodeled nonlinear
dynamics. By linearizing the nonlinear MAGLEV suspension
model, a linear state-space disturbance observer (DOB) is
designed to estimate the lumped “mismatching” disturbances.
A new disturbance compensation control method based on
the estimate of DOB is proposed to solve the disturbance
attenuation problem. The efficacy of the proposed approach
for rejecting given disturbance is illustrated via simulations on
realistic track input.
