Modeling of a horizontal active magnetic bearing system with uncertainties in deterministic form

In this paper the derivation of mathematical model of a horizontal active magnetic bearing (AMB) system in deterministic form is presented. The system is open-loop unstable and highly coupled due to nonlinearities inherited in the system such as gyroscopic effect and mass imbalance. Based on the equ...
