Learning-based model augmentation with LFRs

1 code implementation2 Apr 2024 Jan H. Hoekstra, Chris Verhoek, Roland Tóth, Maarten Schoukens

This model structure is able to represent many common model augmentation structures, thus unifying them under the proposed model structure.

Decoupling parameter variation from noise: Biquadratic Lyapunov forms in data-driven LPV control

no code implementations25 Mar 2024 Chris Verhoek, Jaap Eising, Florian Dörfler, Roland Tóth

A promising step from linear towards nonlinear data-driven control is via the design of controllers for linear parameter-varying (LPV) systems, which are linear systems whose parameters are varying along a measurable scheduling signal.

A Linear Parameter-Varying Approach to Data Predictive Control

no code implementations13 Nov 2023 Chris Verhoek, Julian Berberich, Sofie Haesaert, Roland Tóth, Hossam S. Abbas

By means of the linear parameter-varying (LPV) Fundamental Lemma, we derive novel data-driven predictive control (DPC) methods for LPV systems.

Direct data-driven control with signal temporal logic specifications

no code implementations5 Apr 2023 Birgit C. van Huijgevoort, Chris Verhoek, Roland Tóth, Sofie Haesaert

Most control synthesis methods under temporal logic properties require a model of the system, however, identifying such a model can be a challenging task.

Learning Stable and Robust Linear Parameter-Varying State-Space Models

no code implementations4 Apr 2023 Chris Verhoek, Ruigang Wang, Roland Tóth

This paper presents two direct parameterizations of stable and robust linear parameter-varying state-space (LPV-SS) models.

Direct data-driven state-feedback control of general nonlinear systems

no code implementations19 Mar 2023 Chris Verhoek, Patrick J. W. Koelewijn, Sofie Haesaert, Roland Tóth

Through the use of the Fundamental Lemma for linear systems, a direct data-driven state-feedback control synthesis method is presented for a rather general class of nonlinear (NL) systems.

Data-driven Dissipativity Analysis of Linear Parameter-Varying Systems

no code implementations17 Mar 2023 Chris Verhoek, Julian Berberich, Sofie Haesaert, Frank Allgöwer, Roland Tóth

We derive direct data-driven dissipativity analysis methods for Linear Parameter-Varying (LPV) systems using a single sequence of input-scheduling-output data.

Direct data-driven LPV control of nonlinear systems: An experimental result

no code implementations30 Nov 2022 Chris Verhoek, Hossam S. Abbas, Roland Tóth

The LPV data-driven control design that builds on this representation form uses only measurement data from the nonlinear system and a priori information on a scheduling map that can lead to an LPV embedding of the nonlinear system behavior.

Direct Data-Driven State-Feedback Control of Linear Parameter-Varying Systems

no code implementations30 Nov 2022 Chris Verhoek, Roland Tóth, Hossam S. Abbas

We derive novel methods that allow to synthesize LPV state-feedback controllers directly from a single sequence of data and guarantee stability and performance of the closed-loop system, without knowing the model of the plant.

Data-Driven Predictive Control for Linear Parameter-Varying Systems

no code implementations30 Mar 2021 Chris Verhoek, Hossam S. Abbas, Roland Tóth, Sofie Haesaert

Based on the extension of the behavioral theory and the Fundamental Lemma for Linear Parameter-Varying (LPV) systems, this paper introduces a Data-driven Predictive Control (DPC) scheme capable to ensure reference tracking and satisfaction of Input-Output (IO) constraints for an unknown system under the conditions that (i) the system can be represented in an LPV form and (ii) an informative data-set containing measured IO and scheduling trajectories of the system is available.

Convex Incremental Dissipativity Analysis of Nonlinear Systems - Extended version

no code implementations25 Jun 2020 Chris Verhoek, Patrick J. W. Koelewijn, Sofie Haesaert, Roland Tóth

We investigate how stability and performance characterizations of nonlinear systems in the incremental framework are linked to dissipativity, and how general performance characterization beyond the $\mathcal{L}_2$-gain concept can be understood in this framework.
