Abstract
Cyber-physical systems (CPSs) consist of complex systems that combine control, computation and communication to achieve sophisticated functionalities, such as autonomous driving or automated load balancing in smart grids. Their safety criticality demands strong guarantees about correct functioning. Formal verification is an area of computer science that deals with rigorous and automated methods for correctness analysis based on mathematical models of systems and correctness specifications.
In this talk, Prabhakar presents work on formal verification techniques for cyber-physical systems analysis using the framework of hybrid systems. Hybrid systems capture an important CPS feature: mixed discrete-continuous behaviors that arise due to the interaction of complex digital control software (discrete elements) with physical systems (continuous elements).
Prabhakar overviews their technical challenges, AVERIST (Algorithmic VERifier for STability) and novel algorithmic approaches to stability analysis. Stability is a robustness property that captures small perturbations to the initial state or input to a system result in small variations in system behavior.
Finally, Prabhakar presents current research directions including automated design of hybrid control systems and formal analysis of hybrid systems in the presence of uncertainties.
