Research Content

Control means “Controlling the motion of system”. It is core technology for a robot, automotive, motor, etc. Our laboratory focuses on “Control” and we study about to control the motion such as the robot, automotive, haptics, and motor-drive system. In these researches, we carry out the numerical simulation using MATLAB and PSIM as well as the consideration and analysis of this theory. As the results, we verify the effectiveness of our theory by experiments. There are a lot of collaborative research with a company and we participate many conferences every year.
