This paper presents a settling control of a dual-actuator system for hard disk drives. The dual-actuator system consists of a voice coil motor (VCM) as a first stage actuator and a push-pull-type piezo-electric transducer (PZT) as a second-stage actu

To increase the recording density of hard disk drives (HDDs), we developed a push–pull multi-layered piggyback PZT actuator that enables fine positioning by a dual-stage servo system. This PZT actuator consists of 31-mode push–pull multi-layered

The mode switching control (MSC) is a kind of variable-structure control system with switching in only one direction. When the mode is switched from the fast-movement servo mode to the precise-positioning servo mode, the switching time is the initial

A settling response analysis method for hard disk drives has been developed. In this method, the settling response is decomposed into its contributing modes using the Prony method, which is one of the experimental modal analysis methods. These modes

In the design of linear control systems, the existence of unstable zeros makes it difficult to construct many control systems. When the usual digital control scheme is used, unstable zeros appear in the discrete-time model due to the existence of lim

The authors describe the design of a disturbance attenuation control using a stabilized digital inverse system and apply the control to 2nd-order motor control. Experimental results for a DC motor show that the proposed disturbance attenuation contro
