情報機器におけるメカトロニクス制御技術(特別講演〔2〕)

抄録

This paper presents today and future contribution of mechatronic control technology to information devices such as hard disk drives (HDD) and printers. The purpose of this paper is to show one of paths to improve mutual understandings of mechatronics control technologies among various industries. There are so sophisticated control technologies available in each product, but it is very difficult for engineers to understand features or characteristics of the technologies in different areas. In this paper, after brief overviews of HDD, printer, and their control structures, three viewpoints for designing control systems are proposed, which are (1) control structure, single mode or multi-mode, (2) modeling of plant and disturbances, and (3) how to close your feedback loop, semi-closed or full-closed. From these viewpoints, it may be possible to pick up their features from control technologies applied to specific products, improve mutual understandings, and may find analogy of the control technologies among various products.
