<P>PROBLEM TO BE SOLVED: To provide an engine torque ripple controller that effectively suppresses the torque ripple of an engine coupled to a motor-driven generator comprising an SR motor. <P>SOLUTION: The torque ripple controller 50 is provided with the SR motor 20 coupled to the engine, a rotational position detection means 24 that detects the rotational position of the SR motor 20, a pulse interval calculation means 41 that calculates the output intervals of pulses output from the rotational position detection means 24, a pulse interval average value calculation means 42 that calculates the average of the calculated value by the pulse interval calculation means 41, a pulse output state decision means 44 that decides whether the calculated value by the pulse interval calculation means 41 is larger or not than the calculated value by the pulse interval average value calculation means 42, and a current control means 48 that controls a power current or a regenerative current of the SR motor 20 based on the decision results of the pulse output state decision means 44. <P>COPYRIGHT: (C)2007,JPO&INPIT |
