Dynamics and Minimum-Energy Tracking Control for Mechatronic Systems
About
This coming ICICE 2019 conference, Prof. Fung will introduce the dynamic formulations of mechatronic systems (for example, a mechanical system driven by a permanent magnet synchronous motor, PMSM) by Newton’s law, Kirchhoff’s law and Lagrange equations with displacement and charge as variables. The formulation including a mechanical and a circuit equations, which completely describe mechatronic systems. The linear and nonlinear dissipation functions are considered. Firstly, a simple mechatronic system is introduced to be easily understood, and the input electric energy is derived to equal to electric energy summing with the mechanical energy with a weighting factor. Secondly, the industrial applications are introduced and the energy-saving trajectories are designed for tracking control method. Finally, comparisons between the proposed and traditional ones are shown numerically and experimentally. It is found that the proposed method can be performed successfully for the mechatronic systems. Moreover, the methodology can also be applied to any mechatronic system, especially driven by a PMSM.

About
Tsukasa Yoshida received PhD from Saitama University in 1995 on electrocatalytic reduction of CO2 by macromolecular metal complex. Since 1995, he became assistant professor of Gifu University, Japan, 2005-2012 Associate Professor of the same university, and got the present appointment as a full professor of Yamagata University since 2012. He is also the head of Organic Solar Cell Division of Research Center for Organic Electronics (ROEL) of Yamagata University.
Throughout his career, he was engaged in research on processing of thin film and nanomaterials and their use in energy conversion and storage by electrochemical methods. Specifically, he is the pioneer of electrochemical self-assembly of hybrid thin films of inorganic compound semiconductors (such as ZnO and CuSCN) and organic dye molecules from one pot containing all the chemical ingredients. Through research to reveal mechanism of hybridization and to establish methods of control, these hybrid thin films became useful material for realization of flexible dye-sensitized solar cells. While the research on organic solar cells continues to pursuit possibilities of organic charge transfer salts as light absorbers to eliminate voltage losses, his current work stems towards development of energy storage techniques via redox flow batteries and electrocatalytic water splitting and CO2 reduction.
