Assume-guarantee contracts for continuous-time systems

A Saoud, A Girard, L Fribourg - Automatica, 2021 - Elsevier
Many techniques for verifying properties of continuous-time systems are limited to systems of
moderate size. In this paper, we propose an approach based on assume-guarantee …

Compositional synthesis via a convex parameterization of assume-guarantee contracts

K Ghasemi, S Sadraddini, C Belta - Proceedings of the 23rd …, 2020 - dl.acm.org
We develop an assume-guarantee framework for control of large scale linear (time-varying)
systems from finite-time reach and avoid or infinite-time invariance specifications. The …

Composition of behavioural assume–guarantee contracts

BM Shali, A van der Schaft… - IEEE Transactions on …, 2022 - ieeexplore.ieee.org
The growing complexity of modern engineering systems necessitates a method for design
and analysis that is inherently modular. Methods based on using contracts for system design …

Series composition of simulation-based assume-guarantee contracts for linear dynamical systems

BM Shali, HM Heidema… - 2022 IEEE 61st …, 2022 - ieeexplore.ieee.org
We present assume-guarantee contracts for continuous-time linear dynamical systems with
inputs and outputs. These contracts are used to express specifications on the dynamic …

Assume-Guarantee Reinforcement Learning

M Kazemi, M Perez, F Somenzi, S Soudjani… - Proceedings of the …, 2024 - ojs.aaai.org
We present a modular approach to\emph {reinforcement learning}(RL) in environments

Behavioural contracts for linear dynamical systems: input assumptions and output guarantees

BM Shali, AJ van der Schaft… - 2021 European Control …, 2021 - ieeexplore.ieee.org
We introduce contracts for linear dynamical systems with inputs and outputs. Contracts are
used to express formal specifications on the dynamic behaviour of such systems through two …

Contract composition for dynamical control systems: Definition and verification using linear programming

M Sharf, B Besselink, KH Johansson - Automatica, 2024 - Elsevier
Designing large-scale control systems to satisfy complex specifications is hard in practice,
as most formal methods are limited to systems of modest size. Contract theory has been …
