Latest Patents

One of his latest patents is titled "Servo controller method and apparatus for high tracks per inch hard disk drives using a delay accommodating state estimator." This invention addresses the challenges faced by servo controllers, particularly the voice coil motor of hard disk drives. Many control algorithms currently require 80 to 90 percent of the sampling period to compute the next control, which makes computation time delay a critical factor. Hwang's invention accommodates this transport delay into the state estimator and the overall control system. Experimental results from commercial hard drives and simulations demonstrate that this method effectively enhances the stability of the hard disk drive control system by increasing both the phase margin and gain margin. The invention encompasses the method of operating the servo-controller, the apparatus implementing that method, and hard disk drives that incorporate these servo-controllers.
