Hybrid coupling rules for leaderless heterogeneous oscillators: uniform global asymptotic and finite-time synchronization

no code implementations25 Aug 2023 Simone Mariano, Riccardo Bertollo, Romain Postoyan, Luca Zaccarian

We investigate the engineering scenario where the objective is to synchronize heterogeneous oscillators in a distributed fashion.

Enhancing accuracy of finite-dimensional models for lithium-ion batteries, observer design and experimental validation

no code implementations17 Aug 2023 Mira Khalil, Romain Postoyan, Stéphane Raël

The proposed correction leads to a new state space model for which we design observers, whose global, robust convergences are supported by a Lyapunov analysis.

Finite-time stability properties of Lur'e systems with piecewise continuous nonlinearities

no code implementations2 Feb 2023 Simone Mariano, Romain Postoyan, Luca Zaccarian

We analyze the stability properties of Lur'e systems with piecewise continuous nonlinearities by exploiting the notion of set-valued Lie derivative for Lur'e-Postnikov Lyapunov functions.

Transmit power policies for stochastic stabilisation of multi-link wireless networked control systems

no code implementations11 Dec 2022 Alejandro I. Maass, Dragan Nesic, Romain Postoyan, Vineeth S. Varma, Samson Lasaulce

Transmit power design in the control community has recently attracted much attention, and available works mostly consider linear systems or specific classes of non-linear systems with a single-link view of the system.

Stability analysis of optimal control problems with time-dependent costs

no code implementations13 Oct 2022 Sifeddine Benahmed, Romain Postoyan, Mathieu Granzotto, Lucian Buşoniu, Jamal Daafouz, Dragan Nešić

We present stability conditions for deterministic time-varying nonlinear discrete-time systems whose inputs aim to minimize an infinite-horizon time-dependent cost.

Robustifying Event-Triggered Control to Measurement Noise

no code implementations2 Sep 2022 Koen J. A. Scheres, Romain Postoyan, W. P. Maurice H. Heemels

The general framework is applied to point stabilization and consensus problems as particular cases, where we show that, under similar assumptions as the original work, existing schemes can be redesigned to robustify them to measurement noise.

Event-triggered Control From Data

no code implementations24 Aug 2022 Claudio De Persis, Romain Postoyan, Pietro Tesi

We present a data-based approach to design event-triggered state-feedback controllers for unknown continuous-time linear systems affected by disturbances.

Distributed Periodic Event-triggered Control of Nonlinear Multi-Agent Systems

no code implementations13 Feb 2022 Koen J. A. Scheres, Victor S. Dolk, Michelle S. Chong, Romain Postoyan, W. P. Maurice H. Heemels

We present a general emulation-based framework to address the distributed control of multi-agent systems over packet-based networks.

Transmission power policies for energy-efficient wireless control of nonlinear system

no code implementations18 Nov 2021 Vineeth S. Varma, Romain Postoyan, Daniel E. Quevedo, Irinel-Constantin Morarescu

We present a controller and transmission policy design procedure for nonlinear wireless networked control systems.

Event-Triggered State Estimation with Multiple Noisy Sensor Nodes

no code implementations10 Aug 2021 Koen J. A. Scheres, Michelle S. Chong, Romain Postoyan, W. P. Maurice H. Heemels

We assume that the system has multiple sensor nodes, affected by measurement noise, which can transmit at discrete (non-equidistant) points in time.
