A control system for an induction motor includes a power presumption circuit for presuming an electric energy Fo, which is associated with a reactive power generated in the induction motor, on the basis of the numerical constants including the secondary winding resistance, the actual primary current and the actual rotation speed or angle of the induction motor. The electric energy Fo is used to compensate for the change of the numerical constants of the induction motor, which is caused by the change in temperature.
