The Control Systems Laboratory focuses on designing and developing strategies for control of electrical systems. Our current research areas include Motor control and its analysis, Power electronics, Vibration suppression control, Motion control, Robotics, and Haptics

  1. Suppression Control Method for Torque Vibration of PMSM Using Acceleration Sensor
    The servo motor systems with the PMSM have been widely used for industry applications, home electric appliances, and so on, due to the progress of the power electronics, because of simple structure, easy maintenance, high efficiency, etc.. However, the PMSM produces torque ripple which causes mechanical vibration and acoustic noise. In this research, we propose a suppression control method of the vibration for PMSM utilizing the repetitive control, Fourier transform and a vibration signal acquired by an acceleration sensor attached to the motor frame.

  2. Studies related to Motion control, Robotics, and Haptics
    The main target is to mechanize current manual-handling tasks such as machine assemblies, physical exertion assistances, rescue works on a disaster area. Here, the mechanization indicates remote operations, semi-automations, and full automations. Not only softwares but also machine equipments, analog circuits, and digital circuits are researched to achieve the high performance.
