摘要：In this article, the authors aim to study the state estimation problem under the stochastic event-triggered (SET) schedule. A posterior-based SET mechanism is proposed, which determines whether to transmit data by the effect of the measurement on the posterior estimate. Since this SET mechanism considers the whole posterior probability density function, it has better information screening capability and utilization than the existing SET mechanisms that only consider the first-order moment info...

摘要：The methodology of the unit sliding mode control design (known since 1970s) for linear systems is revised based on the concept of the generalized homogeneity. The restriction about a consistency of the number of control inputs with the dimension of the sliding surface is eliminated. A simple procedure of control parameters tuning based on a known maximal magnitude of matched perturbations is developed. To deal with perturbations of unknown magnitude, a homogeneous sliding mode control with int...

摘要：This article is concerned with analytical developments of results first introduced by Lu et al. (2019). These developments are devoted to the optimization of upper bounds of the interval covariance matrices appearing in the interval Kalman filter. The proposed study is mainly highlighted through two aspects. First, the optimization is further performed by considering a class of upper bounds and minimizing the traces of these bounds in two stages (in terms of a gain matrix and then with respect...

摘要：This article presents algorithms to solve analysis and controller synthesis problems for dynamical systems modeled as a recurrent single-hidden-layer rectified linear unit neural network (ReLU NN), or equivalently, a piecewise affine dynamical system. Such models are interesting since they may arise through the use of modern machine learning methods for system identification, or as closed-loop solutions in certain classes of model predictive control (MPC) problems. A key idea in the proposed a...

摘要：In this article, we consider the static output feedback control for linear quadratic regulator problems with structured constraints under the assumption that system parameters are unknown. To solve the problem in the model free setting, we propose the policy gradient algorithm based on the gradient projection method and show its global convergence to epsilon-stationary points. In addition, we introduce a variance reduction technique and show both theoretically and numerically that it significa...

摘要：This article aims to develop a general and designable distributed algorithm for solving linear algebraic equations (LAEs), which departs from the design framework based on orthogonal projection. The concept of adjustable domains for the parameter matrix is introduced, enabling the algorithm to derive flexible and variable updating rules for agents. By leveraging adjustable domains in control design, all agents can exponentially converge to a common (least squares) solution of (un)solvable LAEs...

摘要：In this article, we propose a solution to the problem of achieving global consensus of the states of scalar integrator systems over a directed graph when the network connecting the agents is available only at isolated (and possibly aperiodic) time instances. We propose decentralized consensus protocols that, using such intermittent information obtained at communication times, globally and asymptotically drives the values of their states to an agreement value, with stability and robustness to p...

摘要：We address differential privacy for fully distributed optimization subject to a shared inequality constraint. By co-designing the distributed optimization mechanism and the differential-privacy noise injection mechanism, we propose the first distributed constrained optimization algorithm that can ensure both provable convergence to a global optimal solution and rigorous $\epsilon$-differential privacy, even when the number of iterations tends to infinity. Our approach does not require the Lagr...

摘要：Despite the fact that many distributed resource allocation (DRA) algorithms have been reported in the literature, it is still unknown how to allocate resources optimally over multiple interacting coalitions. One major challenge in solving such a problem is that the relevance of one coalition's decision to other coalitions' benefits may lead to conflicts of interest among these coalitions. Within this context, a new game model is formulated in the present note, termed as resource allocation gam...

摘要：A new dynamic-scaling-based global adaptive quantized control approach is proposed for nonlinear systems with input and state quantization, which reduces some conservatism of relevant results, including matched nonlinearities, global Lipschitz continuity, and quantization error satisfying constant bound. A unique idea is used to deal with the quantized-state feedback problem, that is, the coefficient deviation problem in the decomposition of sector-bounded quantizer is converted to that of sol...
