Model-Free Design and Analysis of 2DOF PI Controller for Noisy LTI Systems
Taiga Kiyota, Kazuhiro Sato
Set-point tracking for systems with unknown model parameters is a fundamental problem in control, and two-degree-of-freedom (2DOF) Proportional-Integral (PI) controllers -- consist…
Extension of Controllability Score to Infinite-Dimensional Systems
Yuito Nakabe, Kazuhiro Sato
Centrality analysis in dynamical network systems is essential for understanding system behavior. In finite-dimensional settings, controllability scores -- namely, the Volumetric Co…
Performance bound analysis of linear consensus algorithm on strongly connected graphs using effective resistance and reversiblization
Takumi Yonaiyama, Kazuhiro Sato
We study the performance of the linear consensus algorithm on strongly connected directed graphs using the linear quadratic (LQ) cost as a performance measure. In particular, we de…
Controllability scores of linear time-varying network systems
Kota Umezu, Kazuhiro Sato
For large-scale network systems, network centrality based on control theory plays a crucial role in understanding their properties and controlling them efficiently. The controllabi…
NOMADS: Non-Markovian Optimization-based Modeling for Approximate Dynamics with Spatially-homogeneous Memory
Ryoji Anzaki, Kazuhiro Sato
We propose a system identification method, Non-Markovian Optimization-based Modeling for Approximate Dynamics with Spatially-homogeneous memory (NOMADS), for identifying linear dyn…
