Zero-Norm Distance to Controllability of Linear Systems: Complexity, Bounds, and Algorithms
Yuan Zhang, Yuanqing Xia, Yufeng Zhan +1
Determining the distance between a controllable system to the set of uncontrollable systems, namely, the controllability radius problem, has been extensively studied in the past. H…

Perturbation-Tolerant Structural Controllability for Linear Systems
Yuan Zhang, Yuanqing Xia, Gang Wang +1
This paper proposes a notion termed perturbation-tolerant structural controllability (PTSC) to study the generic property of controllability preservation/resilience of structured l…

Observability Robustness under Sensor Failures: a Computational Perspective
Yuan Zhang, Yuanqing Xia, Kun Liu
This paper studies the robustness of observability of a linear time-invariant system under sensor failures from a computational perspective. To be precise, the problem of determini…
