摘要：Optimization problems emerging in most of the real-world applications are dynamic, where either the objective function or the constraints change continuously over time. This article proposes projected primal-dual dynamical system approaches to track the primal and dual optimizer trajectories of an inequality constrained time-varying (TV) convex optimization problem with a strongly convex objective function. First, we present a dynamical system that asymptotically tracks the optimizer trajector...

摘要：In this article, we consider the finite horizon filtering problem of discrete-time Markov jump systems (MJS). In the first part, we consider an MJS satisfying some general nonlinear conditions. It is obtained, for a fixed set of auxiliary constants, filter gains, based on a set of coupled Riccati-like difference equations, that yield a minimum upper bound for the estimation error covariance matrix. When the nonlinear parameters are set to zero, the MJS becomes a Markov jump linear system (MJLS...

摘要：This work deals with the distributed Byzantine-resilient observer (DBRO) design problem for continuous-time high-order integrator multiagent systems on directed graphs, which intends to estimate the leader states accurately in a finite-time interval. A new kind of edge-based DBRO is first formulated for the followers to estimate each order of the nonautonomous leader's state, which is implemented in a cascading manner. Then, the finite-time zero-error estimation performance of the above DBRO i...

摘要：This article presents a dynamic model of multiple self-propelled particles with a periodic controller inspired by the intermittent locomotive behavior in various fish species. The closed-loop dynamics are split into a burst phase during which each particle applies a control input and a coast phase during which each particle performs state estimation. This model allows us to investigate how having nonoverlapping sensing and control affects a system's ability to achieve collective behavior such ...

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：This article solves the problem of almost sure exponential stabilization via output feedback control for stochastic feedforward nonlinear systems with the unknown growth rate. A novel dynamic gain is introduced not only to cope with system uncertainties but also to ensure exponential convergence. Based on this dynamic gain, an adaptive output feedback controller is explicitly constructed. By introducing an improved stochastic analysis method, we rigorously prove that the closed-loop system has...

摘要：This technical note addresses the problem of transforming a single-input-single-output discrete-time system into the extended observer form, which comprise a linear time-invariant observable component, and a nonlinear injection term, which depends on the input, output, and their forward shifts up to a finite order. Intrinsic necessary and sufficient conditions are provided for obtaining the extended observer form via a parametrized state transformation. The conditions are formulated directly i...

摘要：In a Stackelberg game, a leader commits to a randomized strategy and a follower chooses their best strategy in response. We consider an extension of a standard Stackelberg game, called a discrete-time dynamic Stackelberg game, that has an underlying state space that affects the leader's rewards and available strategies and evolves in a Markovian manner depending on both the leader and follower's selected strategies. Although standard Stackelberg games have been utilized to improve scheduling i...

摘要：This article investigates a preset-time and preset-accuracy human-in-the-loop cluster consensus control approach for nonlinear multi-agent systems (MASs) on a directed graph under stochastic actuation attacks. First, a new preset-time and preset-accuracy Zeno-free event-triggered observer that requires neither each agent to access the human agent information nor the first (n-1) derivatives of the human agent output is designed by using a preset-time and preset-accuracy convergence performance ...

摘要：The synthesis problem of the interconnection of homogeneous linear time-invariant systems such that the frequency response satisfies magnitude constraints is investigated. To this end, the usual synthesis approach of traditional filters, viewed as the interconnection of integrators 1/s, is revisited based on the linear fractional transformation representation and the {x,y,z}-dissipative characterization. This approach, based on convex optimization, consists of two steps: the magnitude synthesi...
