초록 ▼

A positioning control system for a controlled device, such as a disk drive head, estimates a moving time for moving the controlled device from a current position of the controlled device to a newly designated position. The system sets the estimated moving time as a target moving time. Positioning elements then move the controlled device to the designated position in response to the target moving time. Positioning elements may include an actuator for moving the controlled device, a position detector for tracking movement of the controlled device, and a control element for controlling the actuator. The control element calculates a trajectory for the controlled device to follow based on the target moving time, and controls the actuator based on the calculated trajectory and controlled device position as determined by the position detector. The control system may also have a position correcting element included in the control element. The correcting element compares the actual position of the controlled device with a calculated position of the controlled device and makes necessary adjustments.
