Nonlinear Position Stabilizing Control with Active Damping Injection Technique for Magnetic Levitation Systems

This proposal suggests a novel nonlinear position-stabilizing controller for magnetic levitation (MAGLEV) applications. The proposed scheme is devised by combining the active damping injection technique and disturbance observers (DOBs), considering the inherent nonlinear dynamics, as well as paramet...
