<P>PROBLEM TO BE SOLVED: To automatically adjust a learning control parameter to obtain desired suppression effect even if a filter order of a torque pulsation extraction filter is made high. <P>SOLUTION: A method detects a torque pulsation component included in a torque detection value T<SB POS="POST">det</SB>of a real system 33 in a form of n-order complex Fourier coefficients T<SB POS="POST">An</SB>, T<SB POS="POST">Bn</SB>through a torque ripple extraction portion 34, automatically adjusts control parameters Kp, ki so that the complex Fourier coefficients T<SB POS="POST">An</SB>, T<SB POS="POST">Bn</SB>are suppressed to 0 by an I-P control portion 31, and suppresses torque ripples of the rotary electric machine by using n-order compensation currents I<SB POS="POST">An</SB><SP POS="POST">*</SP>, I<SB POS="POST">Bn</SB><SP POS="POST">*</SP>obtained in a decoupling portion 32. In the method, a torque pulsation extraction filter GF is set to be a high-order low pass filter, and learning control automatically adjusts the control parameter by a partial model matching method for matching only a low-order pole controlling a response of the rotary electric machine in n-order compensation currents I<SB POS="POST">An</SB><SP POS="POST">*</SP>, I<SB POS="POST">Bn</SB><SP POS="POST">*</SP>obtained in learning control. <P>COPYRIGHT: (C)2012,JPO&INPIT |
