摘要:In this article, the problem of lossless state compression of Boolean control networks is first investigated. Two compression protocols are introduced, based on which an inequality relation between the smallest compressed state walk and a source state walk is established to search all the eligible compressed state walks. Then, by defining indistinguishable trajectories and utilizing the semitensor product approach, some matrix-based conditions for the solvability of lossless state compression ...

摘要:This article proposes a framework for adaptive synchronization of uncertain underactuated Euler-Lagrange (EL) agents. The designed distributed controller can handle both state-dependent uncertain system dynamics terms and state-dependent uncertain interconnection terms among neighboring agents. No structural knowledge of such terms is required other than the standard properties of EL systems (positive definite mass matrix, bounded gravity, velocity-dependent friction bound, etc.). The study of...

摘要:This article presents a seemingly surprising yet simple solution to the open problem of when and how time-delay nonlinear systems with uncontrollable linearization is stabilizable by linear feedback. We show that if a less aggressive control objective, namely, semiglobal asymptotic stabilization (SGAS) instead of GAS is sought, instantaneous linear state feedback would be sufficient for the control of a class of nonlinear systems with state delays, despite the lack of local exponential stabili...

摘要:Decision-making individuals are typically either a best responder who chooses an action that leads to their immediate success, or an imitator, who mimics the actions of the most successful individuals. Conformist best-responders perceive an action to be successful if enough others have done so, whereas nonconformist ones think of an action as successful if few others have done so. Researchers have studied the asymptotic behavior of populations comprising one or two of these types of decision m...

摘要:The multiple Lyapunov-Krasovskii functionals method plays an important role in exponential stability analysis of switched delay systems under constrained switching. When the method is applied to a switched delay system, the condition that each subsystem should have its own functional is essential. In this article, an improved exponential stability analysis method is presented for nonlinear switched delay systems under constrained switching. This is achieved by weakening the essential condition...

摘要:Least-squares parameter estimation is important in system identification and adaptive control owing to its enhanced performance and robustness compared to gradient-descent parameter estimation. Based on a unified class of uncertain nonlinear systems, we introduce the standard least-squares estimator (LSE) and six variations from the old to the latest ones, namely a filterless LSE, a high-gain LSE, a filtered high-gain LSE, a finite-time LSE, a dynamic regressor extension and mixing (DREM)-base...

摘要:In this article, the recursive filtering problem is investigated for a class of discrete-time stochastic dynamical networks where the data delivery from the sensors to the filter is implemented by a digital communication channel. With the help of the uniform quantization method, an improved encoding-decoding mechanism associated with measurement outputs is first put forward where the decoding error is guaranteed to be stochastically bounded under a certain bit-rate constraint condition. Based ...

摘要:This article proposes a novel sufficient condition for the incremental input-to-state stability of a class of recurrent neural networks (RNNs). The established condition is compared with others available in the literature, showing to be less conservative. Moreover, it can be applied for the design of incremental input-to-state stable RNN-based control systems, resulting in a linear matrix inequality constraint for some specific RNN architectures. The formulation of nonlinear observers for the ...

摘要:In this technical note, the problem of attack detection and secure state estimation in collectively observable cyber-physical systems is considered. First, an attack signal estimator is designed, which theoretically realizes the unbiased estimation of attack signals. Then, the alert, whether the sensor is attacked, is described as a hypothesis testing problem from the perspective of average malicious disturbance power, and a novel attack detection algorithm is designed on this basis. Based on ...

摘要:This article proposes a constrained control framework to solve the moving-target enclosing problem for nonholonomic multirobot systems, where the safety and precision constraints are considered during the encircling motion. Based on bearing measurements, the target-robot and interrobot angles are constrained to satisfy the requirements of limited sensing range and collision avoidance. The precision constraint further guarantees all robots converging to a small neighborhood of the desired enclo...
