The lab uses control technology to drive electric vehicles and electric airplanes.
AboutAbout the lab
The power of control to change the world
The Fujimoto-Shimizu-Gunji-Takano-Nguyen Lab studies control theory and its applications.
The lab develops new control theories and applies them to real devices.
Its subjects are wide-ranging: motion control of electric vehicles, wireless power transfer, power electronics, robots, precision positioning devices, and electric airplanes.
Even when members belong to different professors, they all live exactly the same daily life in the lab.
Key terms
- Control theory
- A mathematically based set of ideas and methods for making machines and devices move as intended
- In-wheel motor
- A system in which motors are built directly into the wheels. It can drive the tires without going through gears or similar components
- Wireless power transfer
- Technology that sends electricity to a distant location without connecting a cable

ResearchResearch themes
The lab studies control theory and its applications, digital control, motion control, robotics, motion control of electric vehicles, wireless power transfer, power electronics, and related topics. It develops new control theories and verifies them on real devices.
*Illustrative imageControl of electric airplanes
This research applies the advantages of electric motors to electric airplanes: their fast torque response, and the fact that they can be placed in a distributed way and controlled independently. The lab has worked on propeller control, extending range through regeneration, and motion control of aircraft that use multiple propellers.
*Illustrative imageMotion control of electric vehicles
The lab studies control of electric vehicles with in-wheel motors, which are motors embedded directly in the wheels. It has developed vehicle attitude control and slip ratio control for slippery road surfaces.
*Illustrative imagePrecision positioning stages
The lab studies control that moves precision positioning stages quickly and accurately. These stages are at the core of equipment for manufacturing semiconductors and flat-panel displays. The lab proposes control methods that suppress vibration and interference between axes, as well as new stage structures.
*Illustrative imageRobot control
This research uses control engineering to solve problems such as resonance and backlash caused by the gears and belts in robot joints. Robots that work alongside humans need force control as well as position control.
