摘要：The notion of network robustness reported in some existing literature well characterizes the graph-theoretic properties of networked agent systems (NASs) with a fixed communication graph for seeking resilient consensus. Yet, our systematic understanding of the graph properties for achieving resilient consensus of NASs with time-varying communication graphs remains limited. This study aims to investigate the resilient consensus problem of NASs with misbehaving agents and time-varying communicat...

摘要：This article addresses the problem of computing fixed-interval smoothed state estimates of a linear time-varying Gaussian stochastic system. There already exist many algorithms that perform this computation, but all of them impose certain restrictions on system matrices in order for them to be applicable, and the restrictions vary considerably between the various existing algorithms. This article establishes a new sufficient condition for the fixed-interval smoothing density to exist in a Gaus...

摘要：In this article, we consider the problem of system identification when side-information is available on the steady-state gain (SSG) of the system. We formulate a general nonparametric identification method as an infinite-dimensional constrained convex program over the reproducing kernel Hilbert space (RKHS) of stable impulse responses. The objective function of this optimization problem is the empirical loss regularized with the norm of RKHS, and the constraint is considered for enforcing the ...

摘要：This article proposes a new aggregative game (AG) model with feedback delays. The strategies of players are selected from given strategy sets and subject to global nonlinear inequality constraints. Both cost functions and constrained functions of players are time varying, which reflects the changing nature of environments. At each time, each player only has access to its strategy set information, and the information of its current cost function and current constrained function is unknown. Due ...

摘要：This article addresses the finite-horizon H-infinity consensus problem for general discrete time-varying multiagent systems with energy-bounded external disturbances and limited network bandwidth resource. A dynamic event-based learning approach is proposed to produce a dynamic discrete-time event-triggered scheme and a dynamic distributed H-infinity consensus protocol. Based on the local state information, the dynamic distributed H-infinity consensus protocol is developed to guarantee the H-i...

摘要：This article addresses the synchronization problem of linear multiagent systems with intermittent communication. To solve this problem, we propose an adaptive distributed control algorithm with edge-based event-triggering mechanisms that differs fundamentally from existing approaches in that it does not employ any form of global topology information and absolute state information. Instead, agents update their control signals and check triggering conditions based on relative state information. ...

摘要：In this article, we discuss the inventory regulation problem of a logistic system composed of a production unit and inventory unit. The production system is characterized by a constant lead time, and the storage unit presents fixed losses due to perishable products. In this study, the system is subject to finite production resources, limited storage capacities, and the customer demands are uncertain in a given range. We address a control strategy to the input time delay system that is subject ...

摘要：This article investigates the robust adaptive event-triggered control (ETC) problem for switched nonlinear systems. A novel robust adaptive controller for nonlinear systems under dwell-time switching is first constructed based on a common virtual control Lyapunov function method using backstepping. Then, a dynamic ETC (DETC) strategy is integrated into the switching controller to constitute an overall solution to the problem under investigation while the challenges caused by interaction of swi...

摘要：The feasibility governor (FG) is an add-on unit for model predictive controllers (MPC) that increases the closed-loop region of attraction by manipulating the applied reference to ensure the underlying optimal control problem is always feasible. The FG requires an estimate of the feasible set of the optimal control problem that underlies the MPC; obtaining this estimate can be computationally intractable for high-dimensional systems. This article proposes a modified FG that bypasses the need f...

摘要：In the model predictive control formulations of trajectory tracking problems, infeasible reference trajectories and a priori unknown constraints can lead to cumbersome designs, aggressive tracking, and loss of recursive feasibility. This is the case, for example, in trajectory tracking applications for mobile systems in the presence of constraints that are not fully known a priori. In this article, we propose a new framework called model predictive flexible trajectory tracking control, which r...
