Secure-by-Construction Synthesis for Control Systems
Bingzhuo Zhong, Siyuan Liu, Marco Caccamo +1
In this paper, we present the synthesis of secure-by-construction controllers that address safety and security properties simultaneously in cyber-physical systems. Our focus is on…
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…
Formal Synthesis of Controllers for Uncertain Linear Systems against -Regular Properties: A Set-based Approach
Bingzhuo Zhong, Majid Zamani, Marco Caccamo
In this paper, we present how to synthesize controllers to enforce -regular properties over linear control systems affected by bounded disturbances. In particular, these control…
Sandboxing Controllers for Stochastic Cyber-Physical Systems
Bingzhuo Zhong, Majid Zamani, Marco Caccamo
Current cyber-physical systems (CPS) are expected to accomplish complex tasks. To achieve this goal, high performance, but unverified controllers (e.g. deep neural network, black-b…
Automata-based Controller Synthesis for Stochastic Systems: A Game Framework via Approximate Probabilistic Relations
Bingzhuo Zhong, Abolfazl Lavaei, Majid Zamani +1
In this work, we propose an abstraction and refinement methodology for the controller synthesis of discrete-time stochastic systems to enforce complex logical properties expressed…
Safe-visor Architecture for Sandboxing (AI-based) Unverified Controllers in Stochastic Cyber-Physical Systems
Bingzhuo Zhong, Abolfazl Lavaei, Hongpeng Cao +2
High performance but unverified controllers, e.g., artificial intelligence-based (a.k.a. AI-based) controllers, are widely employed in cyber-physical systems (CPSs) to accomplish c…
Software Fault Tolerance for Cyber-Physical Systems via Full System Restart
Pushpak Jagtap, Fardin Abdi, Matthias Rungger +2
The paper addresses the issue of reliability of complex embedded control systems in the safety-critical environment. In this paper, we propose a novel approach to design controller…
Restart-Based Fault-Tolerance: System Design and Schedulability Analysis
Fardin Abdi, Renato Mancuso, Rohan Tabish +1
Embedded systems in safety-critical environments are continuously required to deliver more performance and functionality, while expected to provide verified safety guarantees. None…
