<P>PROBLEM TO BE SOLVED: To provide a servo control device capable of improving stability, even if error between estimated value and the actual value of load inertia is large and the loads varies. <P>SOLUTION: The servo control unit at least includes a speed regulator 2, into which a difference between a speed command value and a feedback speed is input, and a torque control section 4 for controlling an output torque of a mechanical system 5, based on a torque command value output from the speed regulator 2; and a phase advance compensator 3 is cascad-connected between the speed regulator 2, and for the advance compensator 3, the torque control section 4 automatically adjusts the parameters so that phase advance compensation is performed in the vicinity of the cut-off frequency of the speed regulator 2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
