Practical robust loop-shaping design method for triple-stage HDD actuator control under stroke constraints in data-center storage applications

With the continuous growth of data storage demand, precise and stable magnetic-head positioning in hard disk drives (HDDs) remains essential. This paper proposes a disturbance-rejection-oriented control design for triple-stage actuator (TSA) systems. The approach employs Bode-plo...
