摘要：This article studies the control problem for safety-critical multiagent systems based on quadratic programming (QP). Each controlled agent is modeled as a cascade connection of an integrator and an uncertain non-linear actuation system. In particular, the integrator represents the position-velocity relation, and the actuation system describes the dynamic response of the actual velocity to the velocity reference signal. The notion of inputto-output stability is employed to characterize the esse...

摘要：In this note, the control problem for discrete-time hidden semi-Markov jump systems is investigated under the situation that the system modes are unavailable directly. Compared with the previous results, the case when both system modes and states are immeasurable simultaneously is fully considered and an observer-based control scheme is established for discrete-time hidden semi-Markov jump systems. The random parameters of the systems are subject to a two-layer stochastic process and the under...

摘要：In this work, we study and analyze a class of Duhem hysteresis operators that can exhibit butterfly loops. We study first the consistency property of such operator, which corresponds to the existence of an attractive periodic solution when the operator is subject to a periodic input signal. Subsequently, we study the two defining functions of the Duhem operator such that the corresponding periodic solutions can admit a butterfly input-output phase plot. We present a number of examples where th...

摘要：This article studies finite-time stability (FTS) of impulsive switched systems. Some sufficient criteria based on multiple Lyapunov functions coupled with dwell time condition are derived for ensuring the FTS property. It shows that when the mode governing continuous dynamic is finite-time stable but the discrete dynamic involves destabilizing impulses, the FTS can be guaranteed if the impulses can be effectively restrained by dwell time condition. Conversely, when the mode governing continuou...

摘要：In this article, we initiate the strong structural controllability of Boolean networks (BNs), in order to cope with the difficulty of identifying intricate nodal dynamics. The derived necessary and sufficient criteria for the strong structural controllability of BNs are checkable in a polynomial amount of time. As an interesting feature, controllability is shown to be equivalent to fixed-time controllability in the network-structure regard. We further explore the minimal strong structural cont...

摘要：The contribution of this article is a regional eigenvalue assignment method for cooperative output regulation of heterogeneous linear multiagent systems with an internal model-based distributed dynamic state feedback control law. The proposed method offers an agent-wise local approach to synthesize distributed control gains while assigning, for example, the minimal decay rate and the minimal damping ratio of the overall closed-loop system as desired. Numerical examples demonstrate the efficacy...

摘要：Actor-critic style two-time-scale algorithms are one of the most popular methods in reinforcement learning, and have seen great empirical success. However, their performance is not completely understood theoretically. In this article, we characterize the global convergence of an online natural actor-critic algorithm in the tabular setting using a single trajectory of samples. Our analysis applies to very general settings, as we only assume ergodicity of the underlying Markov decision process. ...

摘要：This article addresses the finite-horizon H-8 filtering problem for a class of discrete time-varying nonlinear systems over high-rate networks whose signal exchanges are scheduled by the FlexRay protocol. To improve the efficiency of the data transmission, a high-rate network is deployed for the measurement signals to be broadcasted from the sensors to the filter. The FlexRay protocol is embedded into the high-rate network to orchestrate the transmission rule of the signals with different attr...

摘要：In this article, we consider the problem of designing an expected-revenue-maximizing mechanism for allocating multiple nonperishable goods of k varieties to flexible consumers over T time steps. In our model, a random number of goods of each variety may become available to the seller at each time, and a random number of consumers may enter the market at each time. Each consumer is present in the market for one time step and wants to consume one good of one of its desired varieties. Each consum...

摘要：In this article, an event-triggered online learning problem for Lipschitz continuous systems with nonlinear model mismatch is considered, with the aim of building a data-efficient nonparameteric estimation approach for learning-based control. The system considered is composed of known linear dynamics and unknown nonlinearity, and the main focus of this work includes the design and analysis of event-triggered learning mechanisms, and the application of the learning method to adaptive model pred...
