MOTOR CONTROLLER

摘要

A normal revolution number calculation unit (151) calculates a normal revolution number (Nn) of a driving motor generator in every control period, based on a signal from a rotational position sensor. A moving average calculation unit (152) calculates a moving average revolution number (NAn) of the normal revolution number (Nn) given in every control period. A predicted revolution number calculation unit (153) determines whether or not the revolution number of the motor generator is in an increasing state, from the locus of the moving average revolution number (NAn). Determining that the revolution number of the motor generator is in the increasing state, the predicted revolution number calculation unit (153) calculates a predicted revolution number based on respective moving average revolution numbers in the present and preceding control periods. The calculated predicted revolution number is set to be used as a control revolution number (MRN2) and output to a motor control unit and a torque command calculation unit (156).
