Laboratory Introduction

Modern high-tech engineering requires a study of multi-disciplinary research for integrated systems composed of mechanics, electronics, hydraulics, and optics, etc. To meet this ends, it is essential to have a wide knowledge and understanding of the system level technology as well as the unit component level technology such as sensors and actuators.

For this purpose, the main research interests in our lab are focused on design, modeling, analysis, control, and simulation of multi-disciplinary mechatronic systems. There are three research areas; Control of mechatronic systems, Design of sensing/actuating systems and its application, and Analog/Digital signal processing.
