Control performance comparison of PZT microactuator driven by voltage and current amplifiers in HDD dual-stage systems
In this paper, we investigate the effect of voltage and current amplifiers for PZT microactuators on the control performance of dual-stage servo systems in hard disk drives (HDDs), where the PZT microactuator is used as a ...
Analysis of actuator in-phase property in terms of control performance and integrated plant/controller design using a novel model matching method
This paper is concerned with resonance in-phase property of a VCM (voice coil motor) plant system in the sense of control performance in HDDs (hard disk drives). Its relationships with the optimal performance level γopt, ...
