SALA BIANCA 11:30―13:10 | SALA TURCA | | | CHAIR | Maurizio Zuffada, Italy | Cesare Fantuzzi, Italy | CO-CHAIR | Winncy Du, USA | Graduate Mechatronics Education in the Department of Mechanical Engineering at the University of Utah
Sanford Meek, Robert Roemer, Mark Minor, University of Utah, USA
The Department of Mechanical Engineering at the University of Utah has been a leader in the development and delivery ofmechatronics education. Firstly we have developed a basic course that is arequired class for all mechanical engineering students. Secondly we offeran undergraduate Certificate of Mechatronics which provides a recognitionfor the student of more advanced work in the area. We are now implementing a graduate certificate program. There are two motivations for a graduate certificate program. First it is intended to be an outreach to working engineers who do not have the time or need for a full graduate degree. Second it is part of several graduate certificates that in combination can become the major part of a Master's Degree. The anticipated result of this approach will be an increase … | 11:30―11:50 | High-Bandwidth Servo Control Designs for Magnetic Disk Drives
Masahito Kobayashi, Shinsuke Nakagawa, Takenori Atsumi, Takashi Yamaguchi, Hitachi Ltd., Japan
In order to attain high track density a head must accurately follow position information recorded on a disk. To achieve high accuracy head positioning disk drives require increased servo bandwidth. However servo bandwidth is restricted by the main resonance frequency of an actuator and by the sampling frequency. In this paper we discuss several servo technologies for high TPI. First we present the limit of the servo bandwidth of digital loop-shaping servo methods to the mechanical resonance at which the main resonance frequency of a VCM actuator is 5 kHz and the sampling time is 30 us. We show that the 1.5 kHz servo bandwidth can be attained by using a phase stabilized compensation method. It is also shown that by using the main resonance pole zero compensation method drawn from H-infinity …
| Mechatronics Training on Source Separation Analysis Using a Gyroscopic Motion of a LEGO’s Robot
Caroline Deltheil, Didier Leandri, Eric Moreau, ISITV, France, Yousef Ibrahim, Monash University, Australia
This paper demonstrates the educational effectiveness through Mechatronics experimental setup using recently-made robot by LEGO. The paper also explains the experimental setup and the Mechatronics educational experience gained by both students and academic staff. Project-based learning of this exercise proved to be a successful vehicle to motivate students and achieve the desired educational objectives. | 11:50―12:10 | Dynamic Model of a Multiple Disk and Spindle Assembly
Gianni Ferretti, Politecnico di Milano, Alberto Furlan, STMicroelectronics, GianAntonio Magnani, Politecnico di Milano, Giuseppe Maiocchi, STMIcroelectronics, Paolo Rocco, Politecnico di Milano, Italy
A simplified dynamic model of a multiple disk and spindle assembly is discussed in this paper. The model is particularly focused at describing the coupling between spindle and disk motion, therefore it is suitable for the design of a spindle motion control aimed at minimizing the vibrations of the disks. The model has been validated by comparison of the resonance frequencies obtained by simulation with experimental results, available in the literature | Remotely Operated Experiment for Mechatronics: Monitoring of DCS on the Internet
K.K. Tan, T.H. Lee, C.Y. Soh, National University of Singapore, Singapore
This paper presents the development of an internet-based system to allow monitoring of important process variables from a distributed control system (DCS). The system is formulated as an add-on to an undergraduate experiment on the development of a desktop DCS. This paper describes the hardware and software design considerations which facilitate the users to access the process variables on the DCS, remotely and effectively, using only a commonly available web browser.
| 12:10―12:30 | Track-following and Seek/settle Control Schemes for High Density Disk Drives with Dual-stage Actuators
Lin Guo, JyeKai Chang, Xiaoping Hu, Maxtor Corporation, USA
Advanced track following and seek/settle schemes for high density hard disk drives with dual-stage actuators are presented. A decoupled master-slave loop structure has been designed for a dual loop system with suspension based piezoelectric micro-actuators. Experiments show significant performance improvements of the dual-actuator system over the conventional single loop servo system. A new settle scheme for dual-stage servo system is also designed using a dual-loop initial value compensation (DIVC) scheme. Experimental results shown dramatic improvement of settle time using this new scheme. | Internet Access to a Fluid Power Mechatronics Laboratory
Wayne J. Book, Matthew D. Rouse, Kyle Koeppen, Georgia Institute of Technology, USA
System dynamics is a course that needs physical experiments to realistically represent behaviors of mechatronic systems to students. This paper describes how experiments in fluid power for motion control can be provided over the internet. A hydraulic system was chosen because this important example is absent from hands on experiments in traditional laboratories. Internet access allows the equipment to be fully utilized without the expense, hazards or scheduling conflicts otherwise encountered. The system and its software are described and representative results from experiments are shown.
