The lab develops digital control theory that can be used across a wide range of fields.
AboutAbout the lab
Questioning the roots of control in depth
The Digital Control Lab studies general-purpose control methods that can be used across a wide range of fields, not limited to specific devices.
It takes on the question "What information should an essentially appropriate control input contain?", devising new theories and methods and verifying them through experiments.
Two faculty members each lead their own lab (group), and they cooperate closely in lab seminars and in supervising students' research.
Key terms
- Digital control
- Control in which a digital device such as a computer takes measurements at fixed time intervals and operates a machine
- Discretization
- Expressing a system that changes continuously over time by its values at fixed time intervals
- Digital grid
- A mechanism that divides a power grid into small units and controls the exchange of power using information and communication technology

ResearchResearch themes
The lab pursues control as a foundational technology in depth, aiming to develop universal control methods that can be used across a wide range of fields. Centered on digital control, it covers control theory, systems in general, and power systems for renewable energy.
*Illustrative imageDigital control of physical systems
The lab represents continuously operating physical systems as discrete-time models, and studies the analysis of their behavior and design methods for digital control. It aims to go as far as application to real-world systems.
*Illustrative imagePower grids for renewable energy
To increase the use of renewable energy, the lab works on building a digital grid, which divides a large power grid into small cells controlled with information and communication technology, and on developing devices that control power.
*Illustrative imageDigital control that approaches analog
Using the delta form and focusing on the differences and consistency between continuous time and discrete time, the lab aims, in theory, at better digitization of analog control systems, and verifies it through simulation and experiments.
*Illustrative imageDiscretization of systems described by partial differential equations
The lab studies methods for discretizing systems described by partial differential equations or differential-algebraic equations so that accuracy does not depend on the sampling period.
