摘要：An apparatus for controlling operation of inverter system configured to drive amotor by using an inverter, and to normally operate the motor in a resonance-generatedfrequency band if the resonance occurs, and a method thereof are disclosed, wherein the
method includes detecting a current outputted by an inverter system to a motor, if anoperation frequency of the motor is in a resonance frequency band, converting thedetected current to a d axis current and a q axis current, calculating a difference betweenthe converted d axis current and pre-sampled d axis current (magnetic flux portion),multiplying the calculated difference by a preset comparative control gain to calculate acomparative control voltage, and adding the calculated comparative control voltage to atorque portion voltage responsive to an operation frequency of the motor to generate adriving voltage of the motor.
