Abstract
This paper investigates the stability control for a 2 DOF magnetic levitation
system with uncertain parameters and external disturbance. The electromagnetic
forces between the magnets and coils are obtained by numerical calculation.
Then, an adaptive sliding mode controller is proposed to deal with the
parameter uncertainties in the system matrices. The robust stability of
the closed-loop system is proved by Lyapunov stability theory. Simulation
results are presented to verify the effectiveness of the proposed control
strategy.
