Security Index from Input/Output Data: Theory and Computation
Takumi Shinohara, Karl H. Johansson, Henrik Sandberg
The concept of a security index quantifies the minimum number of components that must be compromised to carry out a stealth attack. This metric enables system operators to assess t…
Distributed Resilient State Estimation and Control with Strategically Implemented Security Measures
Takumi Shinohara, Karl H. Johansson, Henrik Sandberg
This paper addresses the problem of distributed resilient state estimation and control for linear time-invariant systems in the presence of malicious false data injection sensor at…
From Noisy Data to Hierarchical Control: A Model-Order-Reduction Framework
Behrad Samari, Henrik Sandberg, Karl H. Johansson +1
This paper develops a direct data-driven framework for constructing reduced-order models (ROMs) of discrete-time linear dynamical systems with unknown dynamics and process disturba…
Data-Driven Resilience Assessment against Sparse Sensor Attacks
Takumi Shinohara, Karl Henrik Johansson, Henrik Sandberg
We develop a data-driven framework for assessing the resilience of linear time-invariant systems against malicious false-data-injection sensor attacks. Leveraging sparse observabil…
Data-Driven Model Order Reduction of Nonlinear Systems with Noisy Data
Behrad Samari, Henrik Sandberg, Karl H. Johansson +1
Model order reduction techniques simplify high-dimensional dynamical systems by deriving lower-dimensional models that retain essential system characteristics. These techniques are…
Drones that Think on their Feet: Sudden Landing Decisions with Embodied AI
Diego Ortiz Barbosa, Mohit Agrawal, Yash Malegaonkar +5
Autonomous drones must often respond to sudden events, such as alarms, faults, or unexpected changes in their environment, that require immediate and adaptive decision-making. Trad…
