On Completeness of SDP-Based Barrier Certificate Synthesis over Unbounded Domains

no code implementations24 Dec 2023 Hao Wu, Shenghua Feng, Ting Gan, Jie Wang, Bican Xia, Naijun Zhan

Furthermore, motivated by this formulation, we introduce the definition of homogenized systems and propose a complete characterization of a family of non-polynomial barrier certificates with more expressive power.

Correct-by-Construction for Hybrid Systems by Synthesizing Reset Controller

no code implementations12 Sep 2023 Jiang Liu, Han Su, Yunjun Bai, Bin Gu, Bai Xue, Mengfei Yang, Naijun Zhan

Controller synthesis, including reset controller, feedback controller, and switching logic controller, provides an essential mechanism to guarantee the correctness and reliability of hybrid systems in a correct-by-construction manner.

Switching Controller Synthesis for Delay Hybrid Systems under Perturbations

no code implementations22 Mar 2021 Yunjun Bai, Ting Gan, Li Jiao, Bican Xia, Bai Xue, Naijun Zhan

Delays are ubiquitous in modern hybrid systems, which exhibit both continuous and discrete dynamical behaviors.

Learning One-Clock Timed Automata

1 code implementation23 Oct 2019 Jie An, Mingshuai Chen, Bohua Zhan, Naijun Zhan, Miaomiao Zhang

We present an algorithm for active learning of deterministic timed automata with a single clock.

NIL: Learning Nonlinear Interpolants

no code implementations28 May 2019 Mingshuai Chen, Jian Wang, Jie An, Bohua Zhan, Deepak Kapur, Naijun Zhan

Nonlinear interpolants have been shown useful for the verification of programs and hybrid systems in contexts of theorem proving, model checking, abstract interpretation, etc.
