Abstract
In the resonance ratio control, which the authors proposed for
vibration suppression and disturbance rejection in a torsional system,
the estimation speed of the disturbance observer should have been much
faster than the resonance frequency of the controlled system. However,
too fast a disturbance observer sometimes causes an implementation
problem. In this paper, the authors give the optimal speed of the
disturbance observer and propose a novel technique named “slow
resonance ratio control”. It does not have any fast part in the
controller. It also enables us to design the speed control and the
vibration suppression control almost completely independently
