摘要：This article is relevant to appropriately defining the L-2/L-2 Hankel norm of sampled-data systems through setting a general time instant Theta at which past and future are to be separated and introducing the associated quasi L-2/L-2 Hankel operator/norm at Theta. We first provide a method for computing the quasi L-2/L-2 Hankel norm for each Theta, which is carried out by introducing a shifted variant of the standard lifting technique for sampled-data systems. In particular, it is shown that t...

摘要：In this article, we develop a tube-based distributed model predictive full containment control algorithm for leader-following systems with bounded disturbance under dynamic leaders. The proposed algorithm employs knowledge regarding the constraints on states and control inputs to extrapolate their admissible values in the entire predictive horizon. The Kalman filter is utilized to estimate the system states, introducing estimated error. The error and disturbance are both involved in the time-v...

摘要：An iterative proportional-integral interval estimation strategy for linear discrete-time systems is investigated in this article. A sequence iterative proportional-integral observer is built on system output and unknown disturbance iterative estimation. With the help of a structure separation technique, a sufficient condition in terms of linear matrix inequality is proposed to make the observer error system be asymptotically stable. The boundary reachability of the observer error system is ana...

摘要：This article is devoted to the distributed continuous-time optimization problems with time-varying objective functions and time-varying constraints. Different from most studied distributed optimization problems with time-invariant objective functions and constraints, the optimal solutions in this article are time varying and form a trajectory. First, for the case where there exist only time-varying nonlinear inequality constraints, we present a distributed control algorithm that consists of a ...

摘要：In this article, we tackle the problem of when a globally asymptotically stabilizable nonlinear system by either state or output feedback is globally tolerant to input delay. We focus on the case when the continuous system is not stabilizable by linear or smooth feedback, and thus, local exponential stabilizability is not fulfilled. With the aid of the Lyapunov-Krasovskii functional method and weighted homogeneity, we prove that for a multi-input multi-output nonlinear system with homogeneous ...

摘要：In this article, based on discrete orthogonal polynomials and the block $\epsilon$-circulant matrix, we explore a parallel input-independent model order reduction method, which is suitable for the single-input discrete-time systems characterizing nonaffine uncertainty about a scalar parameter. With the explicit difference relations of Charlier polynomials, Meixner polynomials, and Krawtchouk polynomials, the expansion coefficients of the state variable are obtained. Furthermore, we derive an i...

摘要：This article addresses the problem of decentralized state-tracking in the presence of sensor attacks. We consider a network of nodes where each node has the objective of tracking the state of a linear dynamical system based on its measurements and messages exchanged with neighboring nodes notwithstanding some measurements being spoofed by an adversary. We propose a novel decentralized attack-resilient state-tracking algorithm based on the simple observation that a compressed version of all the...

摘要：In this article, input-to-state stability and stabilization conditions in time-delay generalized Persidskii systems are studied. These conditions are formulated in terms of linear matrix inequalities, which may depend on delay values, and be local or global in state-space. Numerical examples of opinion dynamics and the Lotka-Volterra model illustrate the efficiency of the proposed results.

摘要：We study strongly convex distributed optimization problems where a set of agents are interested in solving a separable optimization problem collaboratively. In this article, we propose and study a two-time-scale decentralized gradient descent algorithm for a broad class of lossy sharing of information over time-varying graphs. One time-scale fades out the (lossy) incoming information from neighboring agents, and one time-scale regulates the local loss functions' gradients. We show that assumin...

摘要：In this article, we consider sequential dynamic team decision problems with nonclassical information structures. First, we address the problem from the point of view of a manager who seeks to derive the optimal strategy of the team in a centralized process. We derive structural results that yield an information state for the team, which does not depend on the control strategy, and thus, it can lead to a dynamic programming decomposition where the optimization problem is over the space of the t...
