Abstract
To improve the riding performance and levitation stability of
a high‐speed magnetic levitation (maglev) train, a control strategy based
on mixed H 2/H4 with regional pole placement and model‐reference
controllers are proposed. First, the nonlinear maglev train model is
established, then the proposed system is designed to observe the
movement of a suspension frame and a control strategy based on mixed
H 2/H4 with regional pole placement and model‐reference control
method are proposed. Test and analysis of the proposed system has
been done using MATLAB toolbox for train levitation height, velocity and
current consume. Comparative simulation results show that the mixed
H 2/H4 with regional pole placement control strategy has a better
performance under the condition of step and random train levitation
height.
