A SELF-CONTROLLED MAGLEV SYSTEM [PDF]
Progress In Electromagnetics Research M, 2012 This paper presents a MAGLEV system in which the magnetic suspension is assured by the repulsion of permanent magnets both on the guideway and on the vehicle. Due to the induced currents on a aluminum sheath surrounding the magnets on the guideway, the system intrinsic instability is overcome.

Maglev train levitation control via tracking differentiator with small phase lag
IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.This work proposes an enhanced tracking differentiator to ensure a small phase lag in both filtering and differential signals, The favourable characteristic is obtained by including the system damping and the amplitude factor into the control algorithm that is applied to construct the differentiator. Abstract The levitation control system is a critical
