In this paper, self-sensing control of a micro-actuator for the hard disk drive is presented. The micro-actuator is a suspension driving type. The micro-actuator uses a PZT actuator pair, installed on the assembly of the suspension. The self-sensing micro actuator can be used to form a combined actuation and sensing mechanism. Direct velocity feedback control and positive position feedback control...
The present paper describes a two-degree-of-freedom control of a self-sensing micro-actuator for a dual-stage hard disk drive. The two-degree-of-freedom control system is comprised of a feedforward controller and a feedback controller. Two controllers are designed for the two-degree-of-freedom control system, one for the inverse dynamic model for the feedforward controller and one for the feedback...
The present paper describes a two-degree-of-freedom control of a self-sensing micro-actuator for a dual-stage hard disk drive using neural networks. The two-degree-of-freedom control system is comprised of a feedforward controller and a feedback controller. Two neural networks are developed for the two-degree-of-freedom control system, one for the inverse dynamic model for the feedforward controller...
