A controller (100, 100A) for easily evaluating validity of inertia is provided. A controller (100, 100A) includes: an electric motor (300); an actual operation acquisition unit (301) that acquires an actual operation of the electric motor (300); a model unit (108) that estimates an operation of the electric motor (300) from a current value applied to the electric motor (300) using a model including inertia of the electric motor (300) and a driven body (400) connected to the electric motor (300); an operation signal input unit (106) that applies an operation signal to a control loop of the electric motor (300) for a prescribed period; and an evaluation value calculation unit (111) that calculates an evaluation value for evaluating the inertia on the basis of a difference between an actual operation and an estimated operation in the application period of the operation signal.
