PROBLEM TO BE SOLVED: To solve the problem that an unstable phenomenon occurs due to resonance characteristics of a mechanical system when increasing electric inertia control response because the resonance characteristics of the mechanical system is not taken into account in electric inertia control. SOLUTION: The electric inertia control device includes an observer 101 to which an axial torque detection value and an angular velocity detection value are input and which calculates a roller surface drive force estimation value. An ATR part 103 of the electric inertia control device is designed by a controller design technique called H∞control,μdesign method on the basis of an ATR generalized plant model. The inertia amount corresponding to a roller surface drive force estimation value is input to the ATR part, and any of a power meter angular velocity detection value, a roller angular velocity detection value, and an axial torque detection value is input to the ATR part, so that a torque current command value is generated.
