摘要：
A control apparatus and a control method for an AC electric motor (1) detect DC bus current plural times at predetermined intervals during first and second predetermined periods and multiply vectors having integrated values of detected values during respective periods as elements by an inverse matrix of a matrix having integrated values during respective periods of sine and cosine functions of output voltage phase of an inverter (2) at the moment that detection is made as elements to thereby estimate reactive and active currents.
