Abstract

This paper gives a new passivity based control of active magnetic bearing systems. First we give a new modeling in port-Hamiltonian form of flywheel systems. Second, we give a new passivity based control which does not have any canceling term for the gyroscopic effect unlike the conventional cross-feedback control, and also does not have any gains to make the closed-loop unstable unlike PID feedback control. In this paper, the linear control is especially studied from the viewpoint of comparisons. Finally we give some simulation and experimental results and confirm the validity of the control methodology in the presence of unbalance influence.
