This paper deals with the problem of a servo system design for a typical dual-stage actuator hard disk drive using a so-called discrete-time robust and ...

Three robust design methods are applied, namely, the μ-synthesis, optimal design and loop-shaping design procedure (LSDP).

Two popular methods for controller design for two stage disk drive systems are μ-synthesis, and the PQ method. The PQ method specifically exploits the two-stage ...
