摘要:The problem of trajectory tracking for the underactuated ground vehicle (UGV) subject to the sensor faults is explored in this article. It is focused on the case of the sensor measurements with time-varying drift and bias and the UGV with unknown nonlinear dynamics and inputs coupling, which render the related solutions infeasible. To conquer this challenge, a novel fault-tolerant prescribed performance control approach via a virtual errors-based recursive design is put forward. It steers the ...

摘要:We compensate for scalability issues in control synthesis by developing a hierarchical scheme that splits the control of a high-dimensional nondeterministic linear concrete system into three consecutive steps. First, a low-dimensional abstract model of the concrete system is obtained. A controller is then designed for this abstract system, which is computationally efficient due to the low-dimensionality of the abstract system. Finally, through the use of an interface, the designed abstract con...

摘要:This study investigates a visibility-based pursuit-evasion (PE) game involving a pursuer with a constrained attack range and an evader. In this game, the pursuer and evader maneuver through obstacle environments. The primary objective of the pursuer is to maintain continuous surveillance of the evader while executing attacks when necessary, whereas the evader aims to evade detection and escape the pursuer's visibility as swiftly as possible. This study represents a variant of the PE game, whic...

摘要:In this article, we consider the notion of resilience for cyber-physical systems, that is, the ability of the system to withstand adverse events while maintaining acceptable functionality. We use finite temporal logic to express the requirements on the acceptable functionality and define the resilience metric as the maximum disturbance under which the system satisfies the temporal requirements. We fix a parameterized template for the set of disturbances and form a robust optimization problem u...

摘要:Accurate estimation of long-term risk is essential for the design and analysis of stochastic dynamical systems. Existing risk quantification methods typically rely on extensive datasets involving risk events observed over extended time horizons, which can be prohibitively expensive to acquire. Motivated by this gap, we propose an efficient method for learning long-term risk probabilities using short-term samples with a limited occurrence of risk events. Specifically, we establish that four dis...

摘要:In binary decision-making, individuals often go for a common or a rare action. In the framework of evolutionary game theory, the best-response update rule can be used to model this dichotomy. Those who prefer the common action are called coordinators or conformists, and those who prefer the rare one are called anticoordinators or nonconformists. A finite mixed population of the two types may undergo perpetual fluctuations, the characterization of which appears to be challenging. It is particul...

摘要:Finite automata (FAs) are popular tools to characterize discrete event systems due to their succinctness. However, capturing data flow between systems and their environments using FAs can be challenging for some systems. To address this problem, this article introduces an extension of FAs, called extended finite automata with event parameters (EP-EFAs), where each transition carries a predicate over a tuple of event parameters. The issue of opacity analysis for EP-EFAs is investigated, and ver...

摘要:In this note, the quasi-synchronization problem for coupled nonlinear hyperbolic systems with delays and different external inputs is addressed through a hybrid-trigger-based impulsive pinning control framework. First, a unified control architecture that synergistically integrates event-triggered impulsive control, time-triggered impulsive control, and pinning control is proposed. This hybrid strategy significantly reduces control costs while ensuring bounded synchronization errors and rigorou...

摘要:This article aims to study the geometric control method of the constrained common invariant subspace (CCIS) within the descriptor multiaffine representation (DMAR) of rational parameter systems, which is particularly effective for deriving S-variable linear matrix inequality results. Specifically, novel necessary and sufficient conditions for the existence of CCIS are established, which significantly reduce the required memory storage and address major computational challenges, such that the p...

摘要:We present a distributed algorithm enabling the dynamic tracking of diameter and radius (DR) of time-varying open networks (ON) together with nodes' eccentricities and network size (ES), called DR-ON-ES, which does not require the disclosure of nodes' identity nor any a priori information on the network. The convergence properties of DR-ON-ES are discussed within the framework of open multiagent systems (OMASs): sufficient conditions are provided to ensure that the trajectory of points of inte...
