摘要： A fuzzy controller controls a track seeking operation and a track following operation for an actuator in accordance with a position error between a present position value and a reference value. When the actuator is in track seeking operation, the actuator is accelerated or decelerated based on a velocity error value between an actual velocity value of the actuator and a target velocity value determined from a velocity profile according to the position error. In a deceleration control of the actuator, a fuzzy inference value generated based on the velocity error value and its differentiated velocity error value is used for a control of the actuator, thereby reducing an occurrence of overshooting at a target track.

摘要： A servomotor speed control system includes a ROM table which stores a minimum distance suited for each motor speed. When the minimum distance corresponding to the current motor speed becomes shorter than the current distance from the current motor position to a positioning target point, the instructed speed is reduced to decelerate the servomotor rotation. In a preferred form, the unit of the distance is identical with an interval of a position indicating signal developed from a rotary encoder associated with the servomotor.

摘要： A velocity control device is disclosed having feedforward signal applied to a velocity servo loop. An actuator moves a laser beam spot to a desired track of an optical disk. A displacement of the laser beam spot outputted from the actuator is differentiated by a differentiator and converted to a signal corresponding to the velocity of the movement of the laser beam spot. A signal corresponding to a distance from the present position of the laser beam spot to the desired track is obtained from the displacement and a desired count value, and is inputted to a function generator to thus obtain a square root of the distance. The difference between the square root of the distance and the moving velocity is obtained by a substracter, and a feedforward signal is added to the difference. The feedforward signal is obtained by differentiating a velocity profile with respect to time with a differentiator.

摘要： A method and apparatus of controlling an actuator of disk drive apparatus having an actuator controller arranged to move said actuator to seek a selected disk track. The control signals applied to the actuator controller are determined to cause the actuator to follow the desired velocity profile. Substantial coincidence with the desired profile can be achieved by utilising Fuzzy rules. Specifically, the control signals are determined for deceleration in dependence upon a deceleration constant, the actual velocity of the actuator, and a value determined by Fuzzy rules in dependence upon the difference between the actual velocity of the actuator and the desired velocity of the profile. This enables the track seeking time to be reduced with minimal overshoot at the target track. The said difference between actual and desired velocities is compared with a function of said actual velocity in order to initially cause a switch from acceleration to deceleration.
