    摘要: A servomotor control method capable of preventing an overshoot in positioning a movable part of a machine in the case where the position of the movable part is controlled in a full-closed loop. When an output P1 of a first acceleration/deceleration processing section of a bell-type acceleration/deceleration process becomes "0", a coefficient k3 of incomplete integration is set to a relatively small value .alpha., and a torque limit value TL is set to a relatively small value TLL. The incomplete integration is performed with the coefficient k3 set to the small value, and a torque command TC is limited to the small value, so that an output of the servomotor is reduced and torsion of a mechanical system between the servomotor and the mechanical movable part is canceled. When both the outputs P1 and P2 of the acceleration/deceleration processing sections become "0", the coefficient k3 is set to a relatively large value .beta., and a torque limit value is made larger, to perform the incomplete integration. Then, the output torque of the servomotor is increased gradually to position the movable part at the designated position.

    摘要: A method of controlling a servomotor, characterized by faster convergence of both positional deviations and velocity deviations, higher responsibility as well as an improved resistivity against a disturbance, and being free from any mechanical resonance. An adjustment gain G is increased when a torque command Tc1 received from a conventional velocity control is small, whereas the adjustment gain G is decreased when the torque command Tc1 is large. A torque command Tc2 obtained by multiplying the Tc1 to the output from the velocity control section by the adjustment gain G is supplied to the servomotor. The gain is to be heightened in the case where the positional deviation and velocity deviation are both small and the torque command Tc1 is also small, to thereby ensure a higher responsibility and a rapid convergence. Moreover, the gain is to be suppressed when the torque command Tc1 is large, thus preventing the occurrence of a mechanical resonance.

    摘要: A position control apparatus has a variable gain-type velocity amplifier (115) provided within a servo control circuit, and a low velocity sensing circuit (114) for sensing a predetermined low velocity of a motor (100) immediately before the motor is stopped. When the rotational velocity of the motor (100) drops to the predetermined low velocity immediately before stoppage during orientation control, the velocity amplifier is changed over in response to a signal from the gain of the low velocity sensing circuit (114), thereby raising servo loop gain.
