<P>PROBLEM TO BE SOLVED: To provide a calculation method of a control parameter that calculates at high speed the control parameter of a motor control device stable and smooth in response and high in control responsiveness, and the motor control device that uses the control parameter calculation method. <P>SOLUTION: The calculation method calculates the control parameter of the motor control device that comprises a speed control means that generates a first torque command so that a speed command and the detected speed of a motor coincides with each other, and a torque control means that drives the motor according to the first torque command or a second torque command that is the result of the filter processing of the first torque command. A load frequency characteristic that is a frequency characteristic between the first or the second torque command and a motor speed is obtained (S1), the maximum value of a gain in a frequency range wherein a phase of the load frequency characteristic is -180+α[deg] is obtained by using a prescribed phase margin α (S2), and the control parameter (speed response frequency) of the speed control means is calculated on the basis of the maximum value of the gain (S3). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
