Abstract
A motor-driving control system includes an actuator configured to generate rotational force by driving received current, a current provider configured to provide current to the actuator while repeatedly turning on and off the current at a preset period and duty, and a controller configured to estimate a rotation position or a rotation speed of the actuator in a section in which the current of the current provider is turned on or off and to control the current provider to follow a speed command based on the estimated rotation position or rotation speed.
Claims15
A motor-driving control system, comprising:
- an actuator configured to generate rotational force by being driven using received current;
- a current provider configured to provide current to the actuator while repeatedly turning on and off the current at a preset period and duty;
- and
- a controller configured to estimate a rotation position or a rotation speed of the actuator in a section in which the current of the current provider is turned on or off and to control the current provider to follow a speed command based on the estimated rotation position or rotation speed.
A motor-driving control method comprising:
- providing current, by a current provider, to an actuator configured to generate a rotational force from the current provider while repeatedly turning on and off the current at a preset period and duty;
- estimating, by a controller, a rotation position or a rotation speed of the actuator in a section in which the current of the current provider is turned on or off;
- and
- controlling, by the controller, the current provider to follow a speed command based on the estimated rotation position or rotation speed.
