<P>PROBLEM TO BE SOLVED: To provide a motor drive controller and a controlling method in which stabilized control can be ensured by suppressing the inadvertent oscillation of a control system automatically. <P>SOLUTION: The motor drive controller comprises means (6) for detecting the angle signal (6a) of a motor (5) driven based on a command signal (1a), filter means (10, 11) provided in a feedback loop of the angle signal (6a) and passing specified frequency components thereof, means (16) for detecting the frequency of an angle signal (1b) passing through the filter means (10, 11), and a means (17) for calculating and setting filter coefficients of the filters (10, 11) to suppress the oscillation of a control system (1) based on the output from the frequency detecting means (16). <P>COPYRIGHT: (C)2003,JPO |
