ABSTRACT:
A method for estimating load inertia and system for controlling motor speed using inverse model are provided, suitable for an alternating current (AC) servo module. An inverse system is connected to an actual system to inversely deduce a substantial torque output, wherein when the value of the speed signal generated by the actual system gradually increases, a net inertia ratio is accumulated; whereas when the value of the speed signal generated by the actual system increases to a fixed value, the net inertia ratio is updated.
