Latest Patents

Janghee Lee holds a patent for a "Fuzzy controller for an actuator and the controlling method thereof." This invention focuses on controlling a track seeking operation and a track following operation for an actuator. The fuzzy controller operates based on the position error between the present position value and a reference value. During the track seeking operation, the actuator is accelerated or decelerated according to the velocity error value, which is the difference between the actual velocity and the target velocity derived from a velocity profile. The fuzzy inference value generated from the velocity error and its differentiated value is utilized for deceleration control, effectively minimizing overshooting at the target track.
