Data-Driven Minimum Energy Control for Stochastic Linear Systems with Finite Sample Guarantees
Vaishnavi Sharma, Vaibhav Katewa
The open-loop minimum-energy control (MEC) problem asks for control inputs that minimize the control energy while ensuring the terminal state reaches a desired value. In this paper…
Approximate Stability Radius Analysis and Design in Linear Systems
Ananta Kant Rai, Vaibhav Katewa
The robustness of the stability properties of dynamical systems in the presence of unknown/adversarial perturbations to system parameters is a desirable property. In this paper, we…
Minimum-norm Sparse Perturbations for Opacity in Linear Systems
Varkey M John, Vaibhav Katewa
Opacity is a notion that describes an eavesdropper's inability to estimate a system's 'secret' states by observing the system's outputs. In this paper, we propose algorithms to com…
On Connections between Opacity and Security in Linear Systems
Varkey M. John, Vaibhav Katewa
Opacity and attack detectability are important properties for any system as they allow the states to remain private and malicious attacks to be detected, respectively. In this pape…
Behavioral Feedback for Optimal LQG Control
Abed AlRahman Al Makdah, Vishaal Krishnan, Vaibhav Katewa +1
In this work, we revisit the Linear Quadratic Gaussian (LQG) optimal control problem from a behavioral perspective. Motivated by the suitability of behavioral models for data-drive…
On a Security vs Privacy Trade-off in Interconnected Dynamical Systems
Vaibhav Katewa, Rajasekhar Anguluri, Fabio Pasqualetti
We study a security problem for interconnected systems, where each subsystem aims to detect local attacks using local measurements and information exchanged with neighboring subsys…
On the Robustness of Data-Driven Controllers for Linear Systems
Rajasekhar Anguluri, Abed AlRahman Al Makdah, Vaibhav Katewa +1
This paper proposes a new framework and several results to quantify the performance of data-driven state-feedback controllers for linear systems against targeted perturbations of t…
On the Real Stability Radius of Sparse Systems
Vaibhav Katewa, Fabio Pasqualetti
In this paper, we study robust stability of sparse LTI systems using the stability radius (SR) as a robustness measure. We consider real perturbations with an arbitrary and pre-spe…
