Abstract

In this study, a nonlinear control approach based on the control current switching of the electromagnets is realized experimentally for a flywheel AMB system. The adaptive output backstepping is used to compute nonlinear control currents by accepting that the rotor and AMB parameters are unknown. One of the improvements obtained in this study is the lower energy consumption of the AMB system due to decreased control currents. Simulation and experimental results showed promising improvements for practical implementations.
