Settling control and performance of dual-actuator system for hard disk drives

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 actuator. The settling controller is designed in three steps. In...
