摘要： An accurate load position control is made possible even when rigidity of a load drive system using a motor is relatively low. Load position signal xl is a present-position measurement value of a load, and after compensation in response to a phase delay thereof has been performed by a stability compensation circuit, the high-frequency portion thereof is taken as a control-target position signal xfb by replacing, in a position-signal combination circuit, a motor position signal xm as a present-position measurement value of a motor, and then the control-target position signal xfb is fed back to a position control circuit. Thereby, a torque command signal indicating a torque target value for driving the load is outputted.

摘要： A motor controller calculates a motor torque command based on motor speed and causes a motor to generate a torque corresponding to the motor torque command, to drive a machine load coupled to the motor. The motor controller includes a speed compensator that makes, when a speed compensation torque is calculated based on the motor speed, frequency characteristics of the speed compensation torque for the motor speed exhibit a low frequency cutoff characteristic so that steady-state gain in frequency response is less than a maximum gain value. A torque adder generates a motor torque command by adding to the existing motor torque command an externally input feedforward torque signal and the speed compensation torque.

摘要： A servo controller includes a mechanical characteristic compensation unit for attenuating components having predetermined frequencies and corresponding to characteristics of a machine, which are included in a position instruction signal corrected by a finite impulse response (FIR) filter, and computing feed-forward signals respectively associated with position, speed, and torque of the machine, and a feedback compensation unit for driving the machine according to the feed-forward signals. Therefore, the servo controller can reduce vibrations that originate from the characteristics of the machine. In addition, because the FIR filter can easily make the response path with respect to a symmetrical instructed path, become symmetrical, when the machine is made to travel between two positions along the same path, the two response paths of the round trip match each other, so machined surfaces having no irregularities can be provided when performing reciprocating machining.
