Summary: This passage discusses the impact of dynamic interactions among vertices in complex networked systems on the outcome of dynamical processes. It presents a study on the persistence of interactions based on a descriptor called temporality to quantify and characterize the similarity of time-varying network snapshots. The effects of the resolution at which interactions take place on temporality are also examined.

Summary: This article explores the collective behavior of a group of generic linear agents interacting by random interaction on signed digraphs in the presence of multiple leaders. The global almost sure convergence of the system is solved by using the convergence analysis method of products of infinite substochastic matrices, and the theoretical research results are verified through simulation experiments.

Summary: This paper investigates the consensus problem of a nonlinear multi-agent system with new nonlinear terms in the dynamics. The main contribution is the introduction of these new terms to express the effect of each agent on neighbor agents. The stability analysis is conducted using algebraic graph theory and a multiple discontinuous Lyapunov function approach, and conditions in terms of linear matrix inequalities are derived for achieving consensus.

Summary: This paper proposes a control algorithm for the output regulation problem of nonlinear pure-feedback systems with unknown functions, avoiding assumptions of unknown functions and adopting a non-backstepping control scheme. The method consists of designing a high-gain state observer with disturbance signals, establishing an internal model with the observer state, and proposing a control algorithm based on Lyapunov analysis and neural network approximation theory. The simulation studies demonstrate the effectiveness of the proposed approach.

Summary: This paper investigates the fixed-time practical bipartite tracking problem for networked robotic systems with parametric uncertainties, input disturbances, and directed signed graphs. A new control algorithm is proposed along with a stability analysis method to achieve fixed-time practical bipartite tracking.

Summary: This work focuses on the issue of multiple delay-dependent finite-time fault-tolerant control (FTC) for uncertain switched Takagi-Sugeno (T-S) fuzzy systems with state and input constraints. The models considered include intermittent faults (IFs), exogenous disturbances, and measurement noise. A nonlinear dynamic output feedback controller is proposed for these uncertain switched T-S fuzzy systems, and an augmented system for realizing FTC is derived. Sufficient conditions for robust finite-time H-infinity control are established using piecewise fuzzy Lyapunov function, and finite-time boundedness (FTB) and input-output finite-time stability (IO-FTS) are achieved. The effectiveness and feasibility of the approach are verified through an example.

Summary: In this paper, a general nonlinear model of opinion dynamics incorporating state-dependent susceptibility to persuasion and antagonistic interactions is investigated. Different scenarios of stubborn positives, stubborn neutrals, and stubborn extremists are examined, with interactions forming a signed graph. Theoretical analysis reveals conditions for convergence to equilibrium points or bipartite consensus in certain scenarios. Examples are presented to demonstrate the effectiveness of the theoretical findings.

Summary: We present a simple protocol for generating N-body entangling interactions between trapped atomic ion qubits in a single step. By utilizing qubit state-dependent squeezing operations and displacement forces on the collective atomic motion, full N-body interactions can be achieved. This N-body gate operation allows for the single-step implementation of a family of N-bit gate operations, including the powerful N-Toffoli gate.

Summary: This article investigates ultrafast tracking control for high-order discrete-time multiagent networks based on predictive ability, establishing a distributed multistep prediction algorithm and control strategy to achieve ultrafast tracking control. It also addresses the problem of ultrafast tracking control with an H-infinity performance specification, converting the robustness of the entire multiagent network into separable subsystems. Finally, it provides optimal ultrafast static tracking control design for a single-integrator network with sampled dynamics, validating theoretical results through simulations.

Summary: This article investigates the non-negative scaled edge-consensus (NNSEC) problems in continuous-time and discrete-time networked systems, and extends them to cases with input saturation. Two observer-based algorithms are proposed using neighboring edges' outputs, and the mathematical expressions of control gain matrix and observer gain matrix are derived. The NNSEC of continuous-time systems can be achieved with the obtained observer and control gain matrices based on H-infinity control theory and low-gain feedback technique, while for discrete-time cases, nonpositive control gain matrix and observer gain matrix can achieve NNSEC. Four examples are presented to validate the main results.

Summary: This article addresses the problem of event-triggered-based fixed-time sliding mode cooperative control for leader-follower multiagent networks with bounded perturbation. A terminal integral sliding mode manifold with fast convergent speed is designed, and a distributed consensus tracking control strategy based on event-triggered and sliding mode control is developed to guarantee consensus within a fixed time. The proposed event-triggered control algorithm reduces the update frequency of control law and eliminates Zeno behavior, as demonstrated through simulation examples.

Summary: Latane's social impact theory predicts that recruitment and supportive interactions play a significant role in opinion formation. This study examines a noisy voter model with supportive interactions, where voters are less likely to change their opinions. Two different ways of implementing support are explored: deterring imitation and promoting independence, or just deterring imitation. These assumptions introduce strong drift into the model, affecting the outcome of the model significantly.

Summary: This article discusses the design of dynamic output feedback controllers for quadratic systems to ensure local exponential stability of the origin and increase the estimate of the basin of attraction as much as possible. By introducing a quadratic term in the controller, it allows for consideration in the same class of dynamics as the studied system. The approach involves utilizing a Lyapunov function with respect to the extended state and combining different linearization techniques to obtain linear matrix inequalities for treatment of induced nonlinear inequalities.

Summary: This study proposes a fault tolerant control mechanism based on robust state-feedback model predictive control for linear parameter varying systems subject to faults along the input channels. By using small prediction horizons, the numerical burden of the robust min-max procedure is alleviated, and the FTC system is able to tolerate time-varying saturation of the actuator.

Summary: The purpose of this letter is to provide contributions to the notion of Complete State to Output Controllability (CSOC) for Linear Time Varying (LTV) systems. We establish criteria to ensure CSOC in finite time for LTV systems with direct transmission of the input to the output. Furthermore, we derive an explicit expression of continuous control using a Gramian matrix under the assumption of CSOC in finite time.
