This paper presents an optimal reset control method for a dual-stage actuator servo system in hard disk drives. The dual-actuator system consists of a voice coil motor (VCM) as a first stage actuator and a push-pull-type piezoelectric transducer (PZT) as a second-stage actuator. It is considered as dual-input single-output (DISO) problem. We designed two optimal reset controllers for VCM and PZT,...
This paper presents an optimal reset control (ORC) method for a dual-stage actuator servo system (DSA) in hard disk drives (HDDs). Track seeking performance is investigated and simulation results show that the propose method is able to achieve short settling time and low overshoot.
