摘要:The purpose of this article is to develop a general framework of mean-square robust control in the presence of stochastic multiplicative uncertainties. We consider block diagonally structured stochastic uncertainties of a variety of structures including diagonal scalar, element-by-element, repeated scalar and full-block stochastic processes with prescribed variance bounds, which may arise from multiple sources and can be used to model various communication losses. In an important distinction f...

摘要:The problem of coverage control, i.e., of coordinating multiple agents to optimally cover an area, arises in various applications. However, coverage applications face two major challenges: 1) dealing with nonlinear dynamics while respecting system and safety critical constraints and 2) performing the task in an initially unknown environment. We solve the coverage problem by using a hierarchical framework, in which references are calculated at a central server and passed to the agents' local mo...

摘要:This article mainly investigates the stochastic finite-time annular domain stability (SFTADS) and asynchronous H-infinity control for nonlinear stochastic switching Markov jump systems (SMJSs). First, the criterion of SFTADS of the system is given by the mode-dependent average dwell time method, and two results, which consider particular cases with no switching signal and no Markov jump, are obtained. Second, when there are asynchronous phenomena in both deterministic switching and Markov jump...

摘要:We consider a continuous-time linear time-invariant dynamical system that admits an invariant cone. For the case of a self-dual and homogeneous cone we show that if the system is asymptotically stable then it admits a quadratic Lyapunov function with a special structure. The complexity of this Lyapunov function, in terms of the number of parameters defining it, scales linearly with the dimension of the dynamical system. In the particular case when the cone is the nonnegative orthant this reduc...

摘要:Given a dynamical system with constrained outputs, the maximal admissible set (MAS) is defined as the set of all initial conditions such that the output constraints are satisfied for all time. It has been previously shown that for discrete-time, linear, time-invariant, stable, observable systems with polytopic constraints, this set is a polytope described by a finite number of inequalities (i.e., has finite complexity). However, it is not possible to know the number of inequalities a priori fr...

摘要:In this article, the challenging problem of distributed adaptive observer design for synchronization and formation control of heterogeneous nonlinear cyber-physical-vehicle systems is addressed. Since the heterogeneous systems contain nonidentical nonlinear dynamics and the leader has unknown dynamics composed of an unknown input bound, the error dynamics of the equilibrium point for the heterogeneous nonmonotonic nonlinear systems will be affected, which has not previously been recognized in ...

摘要:This article investigates the differentially private bipartite consensus problem over signed networks. To solve this problem, a new algorithm is proposed by adding noises with time-varying variances to the cooperative-competitive interactive information. In order to achieve the privacy protection, the variances of the added noises are allowed to increase, which are substantially different from the existing works. In addition, the variances of the added noises can be either decaying or constant...

摘要:Recently, a novel discrete-time nonlinear limit cycle model predictive controller for harmonic compensation has been proposed. Its compensating action is achieved by using the dynamics of a supercritical Neimark-Sacker bifurcation normal form at the core of its cost function. This work aims to extend this approach's applicability by analyzing its stability. This is accomplished by identifying the normal form's region of attraction and final set, which enables the use of LaSalle's invariance pr...

摘要:This study provides some methods to analyze robust stabilizability of uncertain plants with an uncertain time delay using arbitrary linear controllers. In this work, an uncertain plant with an uncertain time delay means that the numerator and denominator coefficients and the time delay term of the transfer function of the plant have interval uncertainties. Towards solving the abovementioned problem, first, robust stability is investigated for the closed-loop system in terms of a general class ...

摘要:In many branches of engineering, Banach contraction mapping theorem is employed to establish the convergence of certain deterministic algorithms. Randomized versions of these algorithms have been developed that have proved useful in data-driven problems. In a class of randomized algorithms, in each iteration, the contraction map is approximated with an operator that uses independent and identically distributed samples of certain random variables. This leads to iterated random operators acting ...
