Toward Next Generation Mechatronics and Control

My team and I aim to achieve control performance that pushes the physical limits through innovations in control theory driven by the requirements of cutting-edge industrial and scientific applications. We pursue both performance and robustness through integrated optimization of the entire mechatronic system and controller design, including system identification and learning control. Our application includes precision mechatronics, electrical motors, power electronics, plasma, thermal systems, and pneumatic systems. Through domestic and international industry-academia collaboration, we propose and implement control theory and control system design methods for world-class control targets such as semiconductor manufacturing equipment, railroad systems, and power system equipments to support a sustainable and prosperous society.

Research field 1

Continuing Semiconductor Scaling with Precision Control

We promote the further miniaturization and 3D fabrication of integrated circuits and flat panel displays through high-speed, high-precision control. We perform system identification of multi-input/output systems, data-driven control, learning control, and integrated design of control systems for control targets. Through joint research with equipment manufacturers, we apply control technology to the world’s most advanced semiconductor manufacturing.
Research field 2

New Circuit Breaker Enables High-Voltage DC Power Transmission

To introduce large-scale renewable energy, DC power transmission is necessary. However, there is a challenge that there are no inexpensive breakers for DC without current zero crossing. In response, we have proposed a compact and inexpensive breaker that can interrupt high DC current by combining fuses, semiconductors, and linear motors through industry-academia collaboration. We are conducting fundamental research to improve performance and advancing its application to DC electric railways and DC power grids. Our proposal has been granted international patents, published in international journals, and obtained funding from the government.
Research field 3

Advanced Motion Control for Accurate and Energy-Saving Automatic Train Operation

We are conducting research to realize a safe, accurate, and sustainable railroad system by utilizing communication based train control (CBTC), GPS, etc. We are developing a scaled roller rig in a HILS environment and conduct research on re-adhesion control, learning control, quantization compensation, and dead-time compensation.
