Linear controllers cannot get satisfactory results for active magnetic bearings (AMB) due to the highly nonlinear and open-loop unstable electromechanical dynamics. This paper proposes a combined controller which integrates a fuzzy logic controller (FLC) with a single neuron controller for AMB. The FLC operates with a small single neuron control component(More)
In magnetic bearing systems or other relative devices with multi-sensors which states are not easy to be monitored and tested, multi-valued logic algebra based on sequential variables is suggested to be utilized in the fault diagnosis of the multi-sensors. The states of sensors and devices are both discretized to be three logic values: normal, abnormal and(More)

This study studies an overview of magnetic flywheel energy storage system. Energy storage is an integral part of any critical power system, as this stored energy is used to offset interruptions in the power delivered system from either a utility or an on-site generator. Magnetic flywheel as mechanical batteries using composite rotor, magnetic support(More)
