摘要：In this article, stabilization of systems by delayed noisy states is investigated. The time delays in the stabilizing noisy states are extended into the general form. To support this novelty, the familiar Doob martingale inequality in the continuous version is improved; the equivalence principle, which says that the exponential stability in moment of an anhysteretic stochastic system infers the same property of the corresponding hysteretic system, is extended to the cases with the newly propos...

摘要：A controller synthesis method for state- and input-constrained nonlinear systems is presented that seeks continuous piecewise affine (CPA) Lyapunov-like functions and controllers simultaneously. Nonconvex optimization problems are formulated on triangulated subsets of the admissible states that can be refined to meet primary control objectives, such as stability and safety, alongside secondary performance objectives. A multistage design is also given that enlarges the region of attraction (ROA...

摘要：Multiagent consensus systems are commonly studied in regard to their scalability and performance. Their scalability relies heavily on the underlying communication system and its connectivity. While it is possible to generate a random graph, which exhibits almost surely good connectivity even with a large number of agents, in a plug-and-play setting, where agents should be able to connect and disconnect with minimal interruption, the generation of a new communication network, i.e., graph, each ...

摘要：The vulnerability analysis of remote state estimation with batch-data detectors is investigated in this article. The considered scenario is that sensors measure the process state and transmit measurements to the remote end via wireless networks, where the yielded innovation may be altered by an adversary in an affine form. At the remote end, a detector utilizing batch statistics is deployed to detect anomalies. In this setup, finding the worst-case estimation performance degradation during a d...

摘要：The strong delay-independent stability (DIS) of linear time-invariant-retarded multiple time-delay systems (MTDSs) is studied in the entire delay space. We develop a new one-step discriminant approach utilizing the generalized Dixon resultant, which unveils the necessary and sufficient algebraic condition for the upper frequency bound. The lower frequency bound is rigorously ascertained by further inspecting the zero spectrum. Then, we raise seven postulates concerning the system stability sta...

摘要：Herein, we investigate the asymptotical controllability of continuous-time probabilistic logic control systems (CT-PLCSs) under piecewise constant and right continuous controls (PCRCCs). The theory of an invariant subset for a CT-PLCS controlled by a PCRCC is developed. Based on this theory, we prove that a state is asymptotically reachable from another state under a PCRCC if and only if it is asymptotically reachable under a simple periodic PCRCC; in other words, the control values are pairwi...

摘要：Control barrier functions (CBFs) ensure the safety of controlled dynamical systems by enforcing forward invariance of safe subsets of the state space. First-order CBFs are applicable for systems where the control input appears in the first time derivative of the controlled output. High-order CBFs (HOCBFs) extend the notion of CBFs to systems of any order, following a procedure reminiscent of the recursive design of a control Lyapunov function in backstepping. Asymptotic stability of compact sa...

摘要：This article is concerned with the distributed online saddle point problem for multiagent networks over time-varying graphs. The objective is to design distributed online algorithms for optimizing the accumulation of the time-varying loss functions, and further to analyze the efficiency of the algorithms by utilizing the so-called dynamic regret as a performance measure. To this end, two kinds of distributed online optimization algorithms are developed by considering full-information feedback ...

摘要：In this note, we present an event-triggered robust adaptive control method with flexible prescribed performance for strict-feedback nonlinear systems. Unlike most existing event-triggered control results with only the inputs being triggered, here we introduce a triggering mechanism into the control law and the parameter estimator simultaneously, so that the communication resources are saved. It is worth noting that under the proposed triggering conditions, there are some challenges and difficu...

摘要：We present a novel framework for transferring the knowledge from one system (source) to design a stabilizing controller for a second system (target). Our motivation stems from the hypothesis that abundant data can be collected from the source system, whereas the data from the target system are scarce. We consider both cases where data collected from the source system is noiseless and noisy. For each case, by leveraging the data collected from the source system and a priori knowledge on the max...
