Dual-stage Actuator Design for Hdd Systems via Cnf Control
نویسندگان
چکیده
Dual-stage actuator design for hard disk drives via composite nonlinear feedback control is presented, which consists of a primary actuator, the voice coil motor and a secondary actuator, the suspension piezoelectric microactuator. The first is effective in both track seeking and following stages to produce fast rising time and low overshoot and the latter works in track following stage only to help the primary actuator. The implementations show that the dual-stage actuator does yield better performance compared to the single primary actuator. Copyright c 2002 IFAC

Design and implementation of a dual-stage actuated HDD servo system via composite nonlinear control approach
We consider in this paper the design and implementation of a dual-stage actuated hard disk drive (HDD) servo system, in which an additional piezoelectric actuator is mounted on top of the conventional voice-coil-motor (VCM) actuator to provide a faster and finer response. More specifically, the dual-stage actuated HDD servo system consists of a primary VCM actuator and a secondary suspension pi...

This paper studies the design of a robust output feedback controller subject to actuator saturation. For this purpose, a robust high-gain sliding mode observer is used to estimate the state variables. Moreover, the combination of Composite Nonlinear Feedback (CNF) and Integral Sliding Mode (ISM) controllers are used for robust output tracking. This controller consists of two parts, the CNF part...
متن کاملH ∞ Probabilistic Robust Controller Design for Hdd Servomechanism
Challenges in designing head positioning servo controller suitable for very high density HDD (above 1 Tbits/in) comes from the issues of external and internal disturbances and to make the controller robust in spite of parametric uncertainty. Servomechanism employing dual-stage actuator can achieve bandwidth required for such high TPI and robust control design has been proposed in the past to ad...
متن کاملSuppression of cross-track vibrations using a self-sensing micro-actuator in hard disk drives
In this study we utilize the self-sensing capabilities of piezoelectric micro-actuators in hard disk drives (HDD) to actively suppress in-plane resonance modes of the suspension in an HDD. The self-sensing circuit is based on a tunable capacitance bridge that decouples the control signal from the sensing signal in the micro-actuator. A hybrid modeling technique based on a realization algorithm ...
