In this paper, we introduce the notion of boundary delay equations, establishing a unified framework for analyzing linear time-invariant systems with pure time-delayed boundary conditions. We establish mild sufficient conditions for the existence, uniqueness, and positivity of solutions. Furthermore, we derive spectral criteria for exponential stability. The conditions on the perturbation generalize well-known criteria for the generation of domain perturbations of positive semigroup generators. As an application, we present necessary and sufficient conditions for the exponential stability of positive hyperbolic systems with time-delayed boundary conditions.

The standard Gaussian filter is unable to simultaneously handle the delayed measurement and correlated noise, a common issue in applications like radar/sonar target tracking, autonomous navigation, and networked control systems. To address this limitation, this paper proposes a novel Gaussian filter framework for nonlinear stochastic systems. Within the Bayesian estimation framework, an augmented state is designed to handle the delayed measurement. Furthermore, the conditional Gaussian distribution Lemma is applied to correct the predicted state under correlated noise. The proposed framework, which is a generalization of the standard Gaussian filter, proceeds through three steps: state prediction, state update, and measurement noise update. Thus, suitable numerical methods can be used to solve the high dimensional integrals in the proposed framework. Finally, a commonly used nonlinear growth model in stochastic system is used to verify the effectiveness of the proposed Gaussian filter, in which the extended Kalman filter (EKF) and the cubature Kalman filter (CKF) are used to deal with the high dimensional integrals.

This work addresses the problem of linear system realizations by mammillary and mammillary-like models, offering necessary and sufficient conditions under which a given transfer function can be represented in this form. Compartmental models, particularly mammillary ones, reflect the physiological dynamics of distribution and elimination. This is especially relevant in clinical pharmacology, where model parameters correspond to meaningful biological processes to support interpretability, personalization, and safe drug delivery, such as in total intravenous anesthesia. To conclude, an application to a propofol infusion model illustrates how mammillary realizations can support physiologically interpretable system representations.

This paper investigates the exponential synchronization problem of nonlinear complex networks (CNs) under an event-based asynchronous intermittent pinning control scheme within the framework of time scales. By leveraging the Lyapunov approach and the foundational theory of time scale, we derive novel exponential synchronization criteria that apply to continuous-time, discrete-time, and hybrid continuous-discrete systems. The proposed control strategy ensures exponential synchronization by dynamically adjusting the pinning node set based on a centralized event-triggered mechanism. Key contributions include the introduction of adaptive control gains and the analysis of synchronization under the asynchronous intermittent strategy. The theoretical results are validated through numerical simulations, demonstrating the effectiveness of the proposed method. Our findings generalize existing results by accommodating a unified synchronization treatment across diverse time domains, thereby enhancing the applicability of intermittent control strategies in complex networks.

This paper is concerned with the problem of global asymptotic local exponential stability (GALES) for a new class of time-delay hybrid systems with logical dynamics. Firstly, we establish the mathematical expression of the so-called systems. This class of hybrid systems consists of continuous and logical parts, in which the change of continuous variable is impacted by its past and present states and the logical events. Next, via the semi-tensor product (STP, i.e., Cheng product) of matrices, the algebraic form of the time-delay hybrid is given. Furthermore, the concept of GALES for the time-delay hybrid system is proposed. After that, based on the Lyapunov–Krasovskii approach, a sufficient condition is derived for testing GALES. Finally, a numerical example is presented to illustrate the effectiveness of the theoretical results.

This paper discusses the filtering problem for a type of two-dimensional (2-D) Roesser systems under the weighted try-once-discard (WTOD) protocol. Here, the WTOD protocol is adopted to allocate resources reasonably in a bandwidth-limited communication network. Under this protocol, each sensor measurement is assigned a predefined priority weight. At each sampling instant, only the measurement with the highest weight can be transmitted while the others are discarded. The aim of this work is to design an filter to ensure the asymptotical stability and finite frequency (FF) interference attenuation level for filtering error systems under the addressed communication protocol. Projection lemma and the well-known generalized Kalman–Yakubovich–Popov (GKYP) lemma are carried out to obtain a sufficient condition for the existence of an filter in the presence of the exogenous input with energy bounded, and a set of linear matrix inequalities is then solved to get the filter gain. Finally, illustrative examples are provided to illustrate the usefulness of the proposed results. The contributions of this work are twofold: (1) Considering the WTOD protocol under the Roesser model, it can better reflect the practical engineering; (2) This paper provides a theoretical reference for the filtering problem of the Roesser model under the other communication protocols.

In this paper, we target the problem of having a quadrotor navigate in an area for surveillance where the relative importance is an unknown nonconvex function with multiple local optima. Typical techniques often split the task into a planning phase for the trajectory and a control part to track that reference following the calculated waypoints. A problem arising from any planning strategy is that it requires knowledge of the nonconvex utility function which is not assumed in this setup. We propose a technique where a hybrid system designs the trajectory that is passed as the reference of a backstepping nonlinear controller or a differential flatness-based control law. For handling multiple optima, the system integrates a three-state automaton that supports ascent phases, spiral coverage, and random restarts to prevent revisits and facilitate comprehensive exploration. Numerical simulations show that our approach matches Model Predictive Control (MPC) strategies if the function was assumed to be known, yet requiring much less computation and enabling real-time full inspection of large maps without prior utility knowledge.

This study focuses on the problem of distributed online Nash equilibrium seeking for aggregative games under time-varying constraints and differentially private. The players’ constraint sets are assumed to be non-uniform and time-varying, while their cost functions are deemed to contain sensitive information requiring protection. To characterize the evolution of the time-varying constraints, we employ the one-way Hausdorff distance ensuring that the players’ decisions always stay at the constraints at each time step. For privacy preservation, we mask the players’ gradients with independent Gaussian noise before information exchange among neighbors. By integrating a projected gradient descent approach with a consensus tracking protocol, we develop a distributed online privacy-preserving algorithm that accommodates both time-varying constraints and time-varying communication topologies. We rigorously prove that the proposed algorithm guarantees -differential privacy. Furthermore, we establish a sub-linear dynamic regret, revealing a fundamental tradeoff between the convergence rate of regret and the level of privacy protection. Finally, through numerical simulations implemented on a Cournot game, the theoretical analysis is verified, and the algorithm’s effectiveness is demonstrated.

The communication connectivity of multi-agent system plays a pivotal role in enhancing coverage efficiency in complex environments. The loss of communication connectivity during the coverage process often leads to the failure of cooperative algorithm, which poses a significant challenge for coverage control. To address this issue, this paper proposes a connectivity-aware coverage control algorithm by integrating time-varying constraint sets with projection operations, which ensures persistent connectivity under dynamic conditions. Based on Lyapunov stability theory, a control strategy is developed to ensure the finite-time convergence of multi-agent system to the centroids of their respective subregions. Furthermore, an upper bound on the distance between the centroid and its optimal point is estimated, and the communication connectivity among adjacent agents is rigorously taken into account with the assistance of geometric relationships. Numerical simulations validate the effectiveness of the proposed coverage control approach. This work provides a practical framework for the real-world applications of coverage control algorithms in the fields such as geohazards monitoring based on unmanned aerial vehicles and wireless sensor networks.

This paper considers the problem of event-triggered control (ETC) for Markov jump systems (MJSs) with random consecutive packet losses. According to the Bernoulli distribution of a single packet loss, consecutive packet losses are discussed and the corresponding probability distribution is provided. Considering that packet losses cause old triggered data to be used such that Zeno behavior occurs, a hybrid event-triggering scheme (HETS) including a predetermined fixed triggering lower bound is adopted. Then the influences of consecutive packet losses on triggering scheme are presented and new triggering inequalities are derived based on the number of lost packets. By resorting to Lyapunov function method, sufficient conditions including the number of lost packets and its probability distribution are developed to guarantee the stochastic stability of MJSs. Finally, the parameters of HETS and controller gains are designed and the effectiveness of the developed results is illustrated by two numerical examples.
