摘要：This article proposes several criteria for the distribution of roots of quasi-polynomials of neutral type with complex coefficients. Compared with Pontryagin's results, the derived criteria can be numerically implemented because the interval of the frequency for analyzing the behavior of the quasi-polynomial can be determined. Moreover, some Hurwitz stability criteria to judge whether all the roots of the quasi-polynomials are in the open left-half complex plane are provided. These Hurwitz sta...

摘要：Brandin and Wonham introduced a timed supervisory control framework in 1994. The key innovations arguably were the introduction of tick events to model the passing of time, and the introduction of event forcing. The framework enriches the Ramadge-Wonham framework, albeit with the cost to deal with high modeling and synthesis complexities due to explicit enumeration of ticks. To address these challenges, the framework presented forgoes the explicit enumeration of tick events and instead relies ...

摘要：In this article, we propose a novel dual inexact splitting algorithm (DISA) for distributed convex composite optimization problems, where the local loss function consists of a smooth term and a possibly nonsmooth term composed of a linear mapping. The DISA, for the first time, eliminates the dependence of the convergent step-size range on the Euclidean norm of the linear mapping, while inheriting the advantages of the classic primal-dual proximal splitting algorithm (PD-PSA): simple structure ...

摘要：This study focuses on the problem of asymptotical stabilization of logic dynamical systems (LDSs) under the situation where the only available measurable information is the real-time output. We propose a novel time-invariant control strategy called output-based random control (OBRC), which breaks through the limitation of time-invariant deterministic output feedback (TIDOF). The TIDOF can be regarded as a special type of the OBRC, but the OBRC is capable of stabilizing some LDSs that cannot be...

摘要：This article is concerned with the output feedback exponential stabilization for a flexible beam with tip mass. When there is no disturbance, it is shown that only one noncollocated measurement is enough to exponentially stabilize the original system by constructing an infinite-dimensional Luenberger state observer to track the state and designing an estimated state-based output feedback control law. This essentially improves the existing result in (Conrad et al. 1998) where two collocated mea...

摘要：This article introduces recurrent equilibrium networks (RENs), a new class of nonlinear dynamical models for applications in machine learning, system identification, and control. The new model class admits built-in behavioral guarantees of stability and robustness. All models in the proposed class are contracting-a strong form of nonlinear stability-and can satisfy prescribed incremental integral quadratic constraints, including Lipschitz bounds and incremental passivity. RENs are otherwise ve...

摘要：This article revisits well-studied dynamic decisions in weakly coupled large-population (LP) systems. Specifically, three types of LP decision problems: mean-field game (MG), mean-field team (MT), and mean-field-type control (MC), are completely analyzed in a general stochastic linear-quadratic setting with controlled-diffusion in state dynamics and indefinite weight in cost functional. More importantly, interrelations among MG, MT, and MC are systematically discussed; some relevant and intere...

摘要：Despite being a foundational concept of modern systems theory, there have been few studies on observability of nonlinear stochastic systems under partial observations. In this article, we introduce a definition of observability for stochastic nonlinear dynamical systems, which involves an explicit functional characterization. To justify its operational use, we establish that this definition implies filter stability under mild continuity conditions: an incorrectly initialized nonlinear filter i...

摘要：This note identifies a flaw in the proof of Theorem 16 in (Saboori and Hadjicostis, 2014). It also discusses how the statement of Theorem 16 can be adjusted and provides the corresponding proof.

摘要：This article presents a distributed data-driven predictive control approach using the behavioral framework. It aims to design a network of controllers for an interconnected system with linear time-invariant subsystems such that a given global (network-wide) cost function is minimized while desired control performance (e.g., network stability and disturbance rejection) is achieved using dissipativity in the quadratic difference form. By viewing dissipativity as a behavior and integrating it int...
