<P>PROBLEM TO BE SOLVED: To provide a motor controller wherein when an inertia set value Jn shifts from actual load inertia J, and when there exits disturbance such as friction or the like, these impacts are reduced, impairment of response is suppressed to a minimum, and moreover a stable control system is attained with simple adjustment even to loads of one time to several hundred times. <P>SOLUTION: The motor controller includes a standard speed calculating portion 7 and a gain multiplying portion 8, wherein the standard speed calculating portion computes a standard speed signal vmdl based on any one of a position command, a speed command or a feedforward command, while the gain multiplying portion outputs a speed deviation compensating signal vcomp after increasing by gain times a difference between the standard speed signal vmdl and a speed feedback signal vfb. <P>COPYRIGHT: (C)2008,JPO&INPIT |
