APPARATUS FOR CONTROLLING ROTARY MACHINE

摘要

In a control apparatus, a filter processor filters target torque for a rotary electric machine to suppress a vibrational frequency component of a drivetrain using a filter having a frequency transfer characteristic. A controller performs drive control of the rotary electric machine according to the filtered target torque. A parameter calculator calculates, according to a running condition of the vehicle, a parameter associated with a request value for responsivity of output torque of the rotary electric machine with respect to the target torque. A variable setter variably sets the frequency transfer characteristic of the filter to decrease a degree of attenuation of the vibrational frequency component with an increase of the request value for responsivity of the actual output torque. A limiter limits a rate of change of the degree of attenuation to suppress vibrations of the drivetrain.
