This paper presents a motion control of a stacker crane applying a two-degree-of-freedom control. The two-degree-of-freedom control system consists of a feed forward controller based on an inverse system and a feed back controller with suppressing the vibration effectively and stabilizing. Feedback control of the motion of the stacker crane is derived by considering the time rate of change of the...
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...
This paper presents a motion control of a flexible stacker crane applying a two-degree-of-freedom control. The two-degree-of-freedom control system consists of a feed forward controller based on an inverse system and a feed back controller with suppressing the vibration effectively and stabilizing. Feedback control of the motion of the flexible stacker crane is derived by considering the time rate...
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...
