Abstraction-Based Verification of Approximate Pre-Opacity for Control Systems
Junyao Hou, Siyuan Liu, Xiang Yin +1
In this paper, we consider the problem of verifying pre-opacity for discrete-time control systems. Pre-opacity is an important information-flow security property that secures the i…
Compositional Reinforcement Learning for Discrete-Time Stochastic Control Systems
Abolfazl Lavaei, Mateo Perez, Milad Kazemi +4
We propose a compositional approach to synthesize policies for networks of continuous-space stochastic control systems with unknown dynamics using model-free reinforcement learning…
Constructing MDP Abstractions Using Data with Formal Guarantees
Abolfazl Lavaei, Sadegh Soudjani, Emilio Frazzoli +1
This paper is concerned with a data-driven technique for constructing finite Markov decision processes (MDPs) as finite abstractions of discrete-time stochastic control systems wit…
Synthesizing Safety Controllers for Uncertain Linear Systems: A Direct Data-driven Approach
Bingzhuo Zhong, Majid Zamani, Marco Caccamo
In this paper, we provide a direct data-driven approach to synthesize safety controllers for unknown linear systems affected by unknown-but-bounded disturbances, in which identifyi…
Sandboxing (AI-based) Unverified Controllers in Stochastic Games: An Abstraction-based Approach with Safe-visor Architecture
Bingzhuo Zhong, Hongpeng Cao, Majid Zamani +1
In this paper, we propose a construction scheme for a Safe-visor architecture for sandboxing unverified controllers, e.g., artificial intelligence-based (a.k.a. AI-based) controlle…
Compositional Synthesis of Signal Temporal Logic Tasks via Assume-Guarantee Contracts
Siyuan Liu, Adnane Saoud, Pushpak Jagtap +2
In this paper, we focus on the problem of compositional synthesis of controllers enforcing signal temporal logic (STL) tasks over a class of continuous-time nonlinear interconnecte…
On a notion of entropy for reachability properties
Mahendra Singh Tomar, Majid Zamani
In this work, we introduce a notion of reachability entropy to characterize the smallest data rate which is sufficient enough to enforce reach-while-stay specification. We also def…
Secure-by-Construction Synthesis of Cyber-Physical Systems
Siyuan Liu, Ashutosh Trivedi, Xiang Yin +1
Correct-by-construction synthesis is a cornerstone of the confluence of formal methods and control theory towards designing safety-critical systems. Instead of following the time-t…
