A new scheme to estimate the moment of inertia in the motor drive system in very low speed is proposed in this paper. The
simple estimation scheme, which is usually used in most servo system for low speed operation, is sensitive to the variation of the
machine parameter, especially the moment of inertia. To estimate the motor inertia value, Reduced-Order Extended Luenberger
Observer (ROELO) is applied. The effectiveness of the proposed inertia identification method using the ROELO is verified by
simulation and experiment.
