ABSTRACT:
Control parameters can be easily and precisely adjusted, the response of a motor controller can be highly accurately made at high speed and a vibration can be suppressed to a low level.Even when an inertia is varied during an operation or a viscous friction is high, the inertia or a viscous friction coefficient can be identified by a control parameter adjusting unit (18) for performing a calculation on the basis of a torque command Trefand the speed Vfbof a motor. As a result, control parameters can be easily and precisely adjusted and the response of a motor controller can be highly accurately carried out at high speed and a vibration can be suppressed to a low level.
