LPV Control for Synchronous Disturbance Attenuation in Active Magnetic Bearings

In this research, we consider the problem of suppressing synchronous vibrations in rotors supported by active magnetic bearings. It is observed that the system dynamics are naturally described by an LPV model and the synchronous disturbances are sinusoids with time-varying frequencies. Given this setting, a notion of almost asymptotic regulation is adopted to synthesize LPV controllers. The rotational speed is viewed as the scheduling parameter. The procedure is applied to a model whose parameters are taken from the literature.
