Design of Stochastic Quantizers for Privacy Preservation

no code implementations5 Mar 2024 Le Liu, Yu Kawano, Ming Cao

This insight enables us to use quantization intentionally as a means to achieve the seemingly conflicting two goals of maintaining control performance and preserving privacy at the same time; towards this end, we further investigate a dynamic stochastic quantizer.

Krasovskii Passivity for Sampled-data Stabilization and Output Consensus

no code implementations16 Jun 2023 Yu Kawano, Alessio Moreschini, Michele Cucuzzella

In this paper, we establish the novel concept of Krasovskii passivity for sampled discrete-time nonlinear systems, enabling Krasovskii-passivity-based control design under sampling.

${\mathcal K}$-monotonicity and feedback synthesis for incrementally stable networks

no code implementations20 Jul 2022 Yu Kawano, Fulvio Forni

We discuss the role of monotonicity in enabling numerically tractable modular control design for networked nonlinear systems.

Krasovskii and Shifted Passivity Based Output Consensus

no code implementations4 Jul 2022 Yu Kawano, Michele Cucuzzella, Shuai Feng, Jacquelien M. A. Scherpen

Motivated by current sharing in power networks, we consider a class of output consensus (also called agreement) problems for nonlinear systems, where the consensus value is determined by external disturbances, e. g., power demand.

Learning Stabilizable Deep Dynamics Models

no code implementations18 Mar 2022 Kenji Kashima, Ryota Yoshiuchi, Yu Kawano

When neural networks are used to model dynamics, properties such as stability of the dynamics are generally not guaranteed.

Controller Reduction for Nonlinear Systems by Generalized Differential Balancing

no code implementations5 Nov 2021 Yu Kawano

In this paper, we aim at developing computationally tractable methods for nonlinear model/controller reduction.

Contraction Analysis of Discrete-time Stochastic Systems

no code implementations10 Jun 2021 Yu Kawano, Yohei Hosoe

In this paper, we develop a novel contraction framework for stability analysis of discrete-time nonlinear systems with parameters following stochastic processes.
