Control and Optimization Lab

The lab controls and optimizes robots and drones to make them move as intended.
AboutAbout the lab
Making robots and drones move exactly as intended.
The Control and Optimization Lab studies how to make robots, drones, cars, and other systems move as desired, based on systems and control theory.
A particular focus is the control of multiple vehicles or mobile robots as a group, such as platooning of self-driving cars and coordinated flight of multiple drones.
The lab also works on high-precision control of systems that are digitally controlled by computers, on developing efficient optimization algorithms, and on developing transformable drones.
On the lab's website, it is introduced under the name "Kyushu University Systems and Control Laboratory (Yamamoto-Themelis Lab)."
Key terms
- Sampled-data control
- A method of digitally controlling a continuously moving system with a computer while measuring its state at regular time intervals.
- Cyber-physical system
- A mechanism in which a real-world physical system is controlled through computation in a virtual (cyber) space.
- Lifting
- A technique for handling the problem that information between sampling points is lost.
ResearchResearch themes
The lab conducts broad research on the theory and applications of control, which brings the behavior of a system closer to what is desired. Its work covers control of groups of robots and vehicles, higher-precision digital control, optimization algorithms, and the development of transformable drones.
*Illustrative imageControl of Groups of Autonomous Mobile Robots
This research concerns the control of multiple vehicles or robots, as in platooning of self-driving cars and coordinated flight of multiple drones. The lab addresses how to control the behavior of the whole group when each unit can obtain only nearby information.
*Illustrative imageHigh-Precision Control of Sampled-Data Systems
This theme deals with systems that are digitally controlled by computers, such as robot control and cyber-physical systems. The lab aims at high-precision control by solving the problem of lost information between sampling points using a technique called lifting.
*Illustrative imageDevelopment of Optimization Algorithms
Engineering problems can be viewed as minimizing a function. For example, path planning is the problem of finding the route that minimizes a cost such as distance or time. The lab develops efficient algorithms with applications in control and signal processing in mind.
*Illustrative imageTransformable Drones
Drones are constrained by the fact that they cannot move sideways without tilting their bodies. The lab develops "transformable drones" with a morphing mechanism built into the frame, and designs controllers that keep them flying stably even as they change shape. The aim is applications such as information gathering at narrow disaster sites.
