摘要：In this article, we study the stability analysis and $H_\infty$ controller synthesis problems for networked systems with random transmission delays and packet dropouts that are subject to noisy sampling intervals. The sampling errors and transmission delays are described by an independent and identically distributed sequence of continuous random variables and the transmission delays are assumed to be smaller than the noisy sampling intervals. First, a closed-loop discrete-time stochastic frame...

摘要：This article studies the sampled-data cooperative output regulation problem for linear multiagent systems. First, a novel adaptive distributed continuous-discrete observer is established to recover the leader's state, which, on one hand, only relies on the sampling output of the leader, and on the other hand, does not need to store the sampled message from neighbors. Second, by solely making use of the digital states of both the agent and the distributed observer, a certainty equivalence contr...

摘要：In this article, the robust cooperative output regulation problem for multiagent systems (MASs) with general heterodirectional hyperbolic PIDE-ODE agents is considered. This setup also covers networks of ODEs with arbitrarily long input and output delays. The output of the agents can be defined at all boundaries and in-domain and may depend on the ODE state while disturbances act on the agents in-domain, at the boundaries, the output, and the ODE. The communication network is described by a co...

摘要：Optimization-based state estimation is useful for handling of constrained linear or nonlinear dynamical systems. It has an ideal form, known as full information estimation (FIE), which uses all past measurements to perform state estimation, and also a practical counterpart, known as moving-horizon estimation (MHE), which uses most recent measurements of a limited length to perform the estimation. This work reveals a generic link from robust stability of FIE to that of MHE, showing that the for...

摘要：This article is concerned with the development and use of duality theory for a hidden Markov model (HMM) with white noise observations. The main contribution of this work is to introduce a backward stochastic differential equation as a dual control system. A key outcome is that stochastic observability (resp. detectability) of the HMM is expressed in dual terms: as controllability (resp. stabilizability) of the dual control system. All aspects of controllability, namely, definition of controll...

摘要：We propose a new distributed optimization algorithm for solving a class of constrained optimization problems in which the objective function is separable (i.e., the sum of local objective functions of agents), the optimization variables of distributed agents, which are subject to nontrivial local constraints, are coupled by global constraints, and only noisy observations are available to estimate (the gradients of) local objective functions. In many practical scenarios, agents may not be willi...

摘要：This note investigates the decentralized stabilization problem for a class of interconnected systems in the presence of non-triangular structural uncertainties and time-varying parameters, where each subsystem exchanges information only with its neighbors and only intermittent (rather than continuous) states and input are to be utilized. Thus far to the best of authors' knowledge, no solution exists priori to this work, despite its high prevalence in practice. Two globally decentralized adapti...

摘要：In this article, we propose a new practical synchronization protocol for multiple Euler-Lagrange systems without structural linear-in-the-parameters (LIP) knowledge of the uncertainty and where the agents can be interconnected before control design by unknown state-dependent interconnection terms. This setting is meant to overcome two standard a priori assumptions in the literature concerning uncertainty with LIP structure and absence of interaction among agents before designing the synchroniz...

摘要：In this article, we aim to study the analytical solution of two identical weak pursuers and one strong evader closed-loop game with a one-/two-step Stackelberg approach. Toward this, the basic idea is presented, that is, the solutions of the closed-loop game and an n-step Stackelberg game might be identical. In particular, we develop the optimal one-/two-step Stackelberg strategy for the evader, as well as the optimal state feedback/closed-loop strategy for the pursuers. On this basis, we proc...

摘要：This article discusses the invariant subspaces that are restricted to be external direct sums. Some existence conditions are presented that facilitate finding such invariant subspaces. This problem is related to the decomposition of coupled differential-difference equations, leading to the possibility of lowering the dimensions of coupled differential-difference equations. As has been well documented, lowering the dimension of coupled differential-difference equations can drastically reduce th...
