Generalized Cactus and Structural Controllability of Switched Linear Continuous-Time Systems
Yuan Zhang, Yuanqing Xia, Aming Li
This paper explores the structural controllability of switched linear continuous-time systems. It first identifies a gap in the proof for a pivotal criterion for the structural con…
Functional Observability, Structural Functional Observability and Optimal Sensor Placement
Yuan Zhang, Tyrone Fernando, Mohamed Darouach
In this paper, new characterizations for functional observability, functional detectability, and structural functional observability (SFO) are developed, and based on them, the rel…
Observability Blocking for Functional Privacy of Linear Dynamic Networks
Yuan Zhang, Ranbo Cheng, Yuanqing Xia
This paper addresses the problem of determining the minimum set of state variables in a network that need to be blocked from direct measurements in order to protect functional priv…
On the Reachability and Controllability of Temporal Continuous-Time Linear Networks: A Generic Analysis
Yuan Zhang, Yuanqing Xia, Long Wang
Temporal networks are a class of time-varying networks, which change their topology according to a given time-ordered sequence of static networks (known as subsystems). This paper…
On Polynomially Solvable Constrained Input Selections for Fixed and Switched Linear Structured Systems
Yuan Zhang, Yuanqing Xia, Shenyu Liu +1
This paper investigates two related optimal input selection problems for fixed (non-switched) and switched structured systems. More precisely, we consider selecting the minimum cos…
On real structured controllability/stabilizability/stability radius: Complexity and unified rank-relaxation based methods
Yuan Zhang, Yuanqing Xia, Yufeng Zhan
This paper addresses the real structured controllability, stabilizability, and stability radii (RSCR, RSSZR, and RSSR, respectively) of linear systems, which involve determining th…
Total Unimodularity and Strongly Polynomial Solvability of Constrained Minimum Input Selections for Structural Controllability: an LP-based Method
Yuan Zhang, Yuanqing Xia, Yufeng Zhan
This paper investigates several cost-sparsity induced optimal input selection problems for structured systems. Given are an autonomous system and a prescribed set of input links, w…
Partial Strong Structural Controllability
Yuan Zhang, Yuanqing Xia
This paper introduces a new controllability notion, termed partial strong structural controllability (PSSC), on a structured system whose entries of system matrices are either fixe…
PTSC: a New Definition for Structural Controllability under Numerical Perturbations
Yuan Zhang, Yuanqing Xia
This paper proposes a novel notion for structural controllability under structured numerical perturbations, namely the perturbation-tolerant structural controllability (PTSC), on a…
