Fast Online Reinforcement Learning Control using State-Space Dimensionality Reduction
Tomonori Sadamoto, Aranya Chakrabortty, Jun-ichi Imura
In this paper, we propose a fast reinforcement learning (RL) control algorithm that enables online control of large-scale networked dynamic systems. RL is an effective way of desig…
Disconnection-aware Attack Detection in Networked Control Systems
Hampei Sasahara, Takayuki Ishizaki, Jun-ichi Imura +1
This study deals with security issues in dynamical networked control systems. The goal is to establish a unified framework of the attack detection stage, which includes the four pr…
Parameterization of Retrofit Controllers
Hampei Sasahara, Takayuki Ishizaki, Jun-ichi Imura
This study investigates a parameterization of all retrofit controllers. Retrofit control can accomplish modular design of control systems, i.e., independent design of subcontroller…
Modularity-in-Design of Dynamical Network Systems: Retrofit Control Approach
Takayuki Ishizaki, Hampei Sasahara, Masaki Inoue +2
In this paper, we develop a modular design method of decentralized controllers for linear dynamical network systems, where multiple subcontroller designers aim at individually regu…
