Loop-shaping controller design with the RBode plot for hard disk drives


The controller for the head positioning system of a hard disk drive must have both high performance and high robustness. This paper presents a user-friendly loop-shaping design method employing the Robust Bode (RBode) plot for the head positioning system. By using the RBode plot, control engineers can easily design controllers that can suppress disturbances… (More)
