ABSTRACT:
An apparatus and method for controlling an electric motor is disclosed. The apparatus includes an instruction inputting section for transmitting an instruction for an electric motor or a control object coupled to said electric motor and a prefilter section for outputting a follow-up instruction value by acting on the instruction. The prefilter section has a prefilter concurrently having characteristics of lowered gain at a prescribed frequency and frequencies in the vicinity thereof, and characteristics of limiting the gain in a high range. An instruction follow-up controlling section provides a controlling instruction follow-up so that a quantity of a state of said electric motor or control object follows the follow-up instruction value.
