摘要：In this article, the quantized sampled-data stabilization problem of nonlinear asynchronous switched (NAS) systems is studied. As a first step, semiglobal practical stability results are provided for NAS systems under digitally implemented continuous-time stabilizers and any kind of switching with arbitrarily fixed dwell time. Then, by suitably exploiting the notion of steepest descent switching feedbacks (SDSFs) induced by common Lyapunov functions and the input-to-state stability redesign ap...

摘要：We design specific neural networks (NNs) for the identification of switching nonlinear systems in the state-space form, which explicitly model the switching behavior and address the inherent coupling between system parameters and switching modes. Such coupling is specifically addressed by leveraging the expectation-maximization framework. In particular, our technique will combine a moving window approach in the expectation-step to efficiently estimate the switching sequence, together with an e...

摘要：This article investigates the design of a novel completely distributed unknown input observer (DUIO) for linear time-invariant systems without relying on any global information. Existing methods face significant limitations, such as difficulty in simultaneously achieving asymptotic estimation of both system state and unknown input, substantial increases in observer orders, or even the nonexistence of feasible observers. To address these challenges, a novel DUIO design framework based on interv...

摘要：This article investigates the problem of remote state estimation in cyber-physical systems subject to stochastic stealthy attacks. Unlike existing studies that assume persistent intrusion, the attack success is modeled as a stochastic process, thereby providing a more realistic characterization of adversarial capabilities. A comprehensive analysis is conducted from both short-term and long-term perspectives. In the short-term analysis, the evolution of the estimation error covariance is examin...

摘要：This article is dedicated to robust output regulation for a class of linear minimum-phase systems with guarantee of asymmetric prescribed performance. Through internal model principle, we first construct a so-called augmented system with the considered system and some designed internal models. Then, we convert the prescribed performance robust output regulation problem into the prescribed performance robust stabilization problem of the augmented system with a series of input and coordinate tra...

摘要：In practice, the cache, capable of storing frequently accessed data, is widely deployed in edge servers to guarantee quick retrieval and improve overall system performance. In this article, the moving-horizon state estimation problem is investigated for a class of multisensor systems under the effects of limited caching capacity and sensor resolution. The measurement information collected by multiple sensors is first transmitted to an edge server for state estimation purposes and then stored i...

摘要：Many optimal and robust control problems are nonconvex and potentially nonsmooth in their policy optimization forms. In Part II of this article, we introduce a new and unified extended convex lifting (ECL) framework to reveal hidden convexity in classical optimal and robust control problems from a modern optimization perspective. Our ECL offers a bridge between nonconvex policy optimization and convex reformulations, enabling convex analysis for nonconvex problems. Despite nonconvexity and non...

摘要：In this article, we address the distributed source seeking (DSS) problem using model predictive control (MPC). In our approach, the signal field is modeled as a weighted combination of convex functions, and we employ a distributed set-membership estimation to gain a global exploration of the field. This estimated field is then treated as the output of the resulting connected system, enabling the DSS problem to be formulated as an output tracking problem that can be solved using a distributed a...

摘要：We consider finite Markov decision processes (MDPs) with convex constraints and known dynamics. In principle, this problem is amenable to off-the-shelf convex optimization solvers, but typically this approach suffers from poor scalability. In this work, we develop a first-order algorithm, based on the Douglas-Rachford splitting, that allows us to decompose the dynamics and constraints. Thanks to this decoupling, we can incorporate a wide variety of convex constraints. Our scheme consists of si...

摘要：The ring-patterned control is studied for a class of multiagent systems (MASs) under directed ring interactions with time-varying weights, further accommodating increasing scales and achieving hyperexponential consensus with the dynamic weighted average steady state. For both MAS of scalar-agent and multivariable-agent, ring-patterned control is proposed by encoding the corresponding matrices into respective time-varying polynomials of the time-invariant ring-patterned base matrix. With these ...
