摘要：We establish finite sample certificates on the quality of solutions produced by data-based forward-backward (FB) operator splitting schemes. As frequently happens in stochastic regimes, we consider the problem of finding a zero of the sum of two operators, where one is either unavailable in closed form or computationally expensive to evaluate, and shall therefore be approximated using a finite number of noisy oracle samples. Under the lens of algorithmic stability, we then derive probabilistic...

摘要：Feedforward control is essential for precise output tracking in nonminimum phase (NMP) systems, and stable inversion has been proposed to address input instability caused by unstable internal dynamics. However, this approach demands an accurate mathematical model, limiting its effectiveness in the presence of model uncertainties and especially in cases without a model. While data-driven control (DDC) can enhance performance in these scenarios, it often fails to achieve precise tracking under i...

摘要：Hamilton-Jacobi reachability (HJR) provides a value function that encodes the set of states from which a system with bounded control inputs can reach or avoid a target despite any bounded disturbance, and the corresponding robust, optimal control policy. Though powerful, traditional methods for HJR rely on dynamic programming (DP) and suffer from exponential computation growth with respect to state dimension. The recently favored Hopf formula mitigates this curse of dimensionality by providing...

摘要：To avoid computational overflow in partially homomorphic encrypted control systems with dynamic linear time-invariant (LTI) discrete-time controllers, it has been previously suggested to use controllers possessing integer characteristic polynomials. These controllers are divided into two categories: finite impulse response (FIR) controllers and non-FIR ones. In this article, it is proved that each plant, which is stabilizable by FIR controllers, can also be stabilized by non-FIR ones having in...

摘要：This work studies 1-moment stability for continuous-time Markov jump linear systems under both stationary and time-varying transition rates. For stationary transition rates, we propose novel sufficient stability conditions that are stated in terms of linear programs. These conditions offer a less restrictive and computationally simpler stability characterization compared to the commonly used mean-square stability analysis. Moreover, they offer a simple approach to also investigate the weaker n...

摘要：The estimation of a mixture of real-and integer-valued parameter vectors appears in different control and signal processing applications. In some particular cases, for instance when dealing with covariance or rotation matrices, the real parameter must be constrained by geometrical properties. This article considers the general estimation problem containing both Lie group and integer parameters, for which the corresponding performance bound is a important missing tool. Leveraging recent results...

摘要：This article is concerned with the stability problem of impulsive systems in Lyapunov framework. Different from the traditional stability results, a class of discrete dynamic decomposition methods is introduced in this article, whose key advantage is that it describes the impulsive action by breaking it into different types. It is particularly helpful when the original problem involves complicated impulsive actions, especially for some nonlinear impulses. Based on such method, we propose a nov...

摘要：Many realistic decision-making problems in networked scenarios, such as formation control and collaborative task offloading, often involve complicatedly entangled local decisions, which, however, have not been sufficiently investigated yet. Motivated by this, we study a class of globally constrained decentralized optimization problems with a variable coupling structure that is new to the literature. Specifically, we consider a network of nodes collaborating to minimize a global objective subje...

摘要：This note makes the first attempt to investigate the optimal bipartite consensus problem in the general cas e for heterogeneous multiagent systems with cooperative-competitive interactions, specifically those containing a spanning tree. Unlike traditional control protocols based on the gradient descent method, our proposed optimal bipartite algorithm demonstrates a fast superlinear convergence speed. The key innovation of this method lies in the design of a fully distributed optimal controller...

摘要：A pressing open problem in the study of interconnected dynamical systems is how to gauge the impact higher order interactions have on the onset of collective behaviors. In this article, we describe multibody interactions among systems using the formalism of directed hypergraphs. Introducing the novel concept of circulating hypergraphs, we formulate the synchronization and pinning control problems in hypernetwork dynamical systems. Extending the notion of balanced digraphs to the case of direct...
