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 secondary actuator and works together with the primary actuator of voice coil...
