Summary: This paper discusses the issue of prescribed-time synchronization in networks of piecewise smooth systems. It presents two new lemmas for nonlinear piecewise smooth systems, which allow for arbitrary preset stable time and are independent of control parameters and initial values. The paper also introduces a feedback controller and a novel event-triggered controller to achieve prescribed-time synchronization. The conditions for prescribed-time synchronization are obtained using set-valued analysis technique and generalized Lyapunov functional approach, in terms of linear matrix inequalities (LMIs). Two application examples are provided to validate the obtained results and the effectiveness of the control schemes.

Summary: This article presents new concepts of alpha-passivity and alpha-finite-time passivity (alpha-FTP) for fractional-order systems with different input and output dimensions, extending existing definitions and conditions. The study develops sufficient conditions for alpha-passivity of multi-weighted fractional-order complex dynamical networks (MWFOCDNs) with fixed and adaptive couplings, and discusses synchronization based on alpha-output-strict passivity (alpha-OSP). Additionally, alpha-FTP for MWFOCDNs with fixed and adaptive couplings is studied using a designed state feedback controller, and the relationship between finite-time synchronization (FTS) and alpha-FTP is illustrated. The validity of the obtained criteria is demonstrated through numerical examples and simulation results.

Summary: This article investigates the problem of leaderless consensus in heterogeneous Euler-Lagrange systems connected by multiple networks, where the systems are subject to persistent disturbances with unknown constants. The unique characteristic of this study is that the agents lack information on a common reference model or trajectory. However, by utilizing distributed observers, internal model principles, and adaptive regulation, consensus to a common reference model, consensus to a common reference trajectory, and rejection of unknown disturbances can be achieved. This design extends recent research on group model learning for linear agents in undirected networks to Euler-Lagrange dynamics in directed networks with persistent unknown disturbances.

Summary: This paper investigates the observer-based asynchronous feedback H-infinity control problem for time-varying delay fuzzy implicit jump systems under event-driven strategy. A hidden Markovian model is used to capture the asynchronization mechanism between the modes of controlled system and the modes of controller. By applying free weight matrix method and singular value decomposition technique, new observer-based asynchronous H-infinity control criteria are obtained to guarantee that the delayed fuzzy implicit jump systems satisfy stochastic admissibility with H-infinity performance. The effectiveness and practicality of the results are verified through simulation examples including a practical system of single-link robot arm.

Summary: In this paper, a connectivity-preserving performance function approach is proposed for the distributed output-feedback synchronized tracking of uncertain heterogeneous nonlinear multiagent systems. The approach utilizes a universal output-feedback synchronized control methodology that ensures both initial network connectivity and preselected synchronization performance using a connectivity-preserving performance function with a designable convergence time. The approach includes the design of neural-network-based adaptive observers for each follower to ensure boundedness of estimation errors, and the construction of local event-triggered synchronized trackers using relative output information and the connectivity-preserving performance function in a low-complexity sense.

Summary: This research investigates the fixed-time event-triggered fuzzy adaptive control for uncertain nonlinear systems with full-state constraints. Due to the difficulty of modeling and the inherent characteristics of mechanical structures, uncertainties and state constraints often arise in engineering applications, and the system may suffer from network congestion. Ignoring the effects of these constraints can affect the performance of the system. In addition, the system often requires high convergence speeds to increase productivity. To cope with these problems, this study investigates the fixed-time event-triggered fuzzy adaptive control method, which uses special barrier Lyapunov functions (BLFs) to ensure that the full-state constraints are not violated. A fuzzy based event-triggered mechanism (ETM) is also designed to manage limited communication resources. Simulation results verify the feasibility of the proposed method.

Summary: A general double-layer scheme is proposed to resolve the cooperative output regulation problem of heterogeneous multi-agent systems subject to actuator saturation and faults. In the network layer, an observer generates a reference trajectory for each follower on the directed communication topology, while a semi-global fault-tolerant control strategy compensates for the impact of actuator saturation and faults in the physical layer. The proposed strategy exhibits better generality and a numerical simulation case study verifies its feasibility.

Summary: This article reconsiders fixed-time stability (FXTS) and fixed-time control (FXTC) of dynamic systems using special functions to improve the accuracy of settling time estimate and reduce chattering. New FXTS criteria are established and upper bounds of settling time are calculated, ensuring the most accurate estimates compared to existing results. Additionally, saturation functions are constructed to suppress chattering caused by the sign function, and a new system is obtained through rigorous theoretical analysis. Applications to chaotic systems stabilization and a novel saturation controller for preassigned-time stabilization are also explored, showing improvement over existing methods with time-varying infinite gains. Three numerical examples are provided to verify the improved estimates and chattering reduction.

Summary: This article investigates the fixed-time (FXT) synchronization of discontinuous competitive neural networks (CNNs) with time-varying delays. Two types of discontinuous FXT control schemes are proposed, and two forms of Lyapunov function based on p-norm and 1-norm are constructed to analyze the FXT synchronization of CNNs. By employing nonsmooth analysis and inequality techniques, simple criteria for achieving FXT synchronization and an upper bound of the settling time with less conservativeness are derived. The effect of time scale on FXT synchronization of CNNs is also considered, and numerical results for an example are provided to validate the theoretical findings.

Summary: This paper addresses the synchronization problem of impulsive complex networks with mismatched parameters, focusing on fixed-time (FT) and preassigned-time (PT) synchronization. The research first establishes more succinct conditions to achieve FT stability of impulsive systems and provides an improved estimation for the stable time. Building upon the improved FT stability results, FT synchronization criteria for ICNs with mismatched parameters are proposed by designing fixed-time controllers without the linear part. Correspondingly, the PT synchronization problem is also considered by developing innovative control protocols. The presented synchronization criteria are validated through numerical simulation.
