Our interests include system control theory and mainly we provide some solutions related with networked control systems in theoretical viewpoint. Typical examples are given as follows.

Quantization of control signal

In control systems which contains network communication channels, the resolution of the signals for control is limited because of communication capacity. We establish control design methods which guarantee similar control performance by limited resolution control signals.

Encryption for control systems

If control systems are connected to networks, the systems are exposed to malicious attacks. We are challenging to compose secure systems against such attacks.

Multi-agent control system

A multi-agent system consists of multiple small subsystems connected by a network. They communicate with each other and achieve a global objective with local information. We study various problems for such systems.
