• Adaptive Stabilization of Uncertain Linear System With Stochastic Delay by PDE Full-State Feedback AI翻译
  作者：Zhang, Zhengqiang; Fang, Qin; Chen, Xinkai

  摘要：This article focuses on the equilibrium regulation problem of a class of uncertain linear systems with stochastic input delay, where the delay is modeled as a Markov process with finite states. Our approach is based on the partial differential equation backstepping method. We first consider the Markov delay with finite known states. An adaptive controller is designed to achieve global almost sure asymptotic convergence. Then, the Markov delay with finite unknown states is discussed. Owing to t...
• Consensus for a Class of Multiagent Systems With Time Delays: A Systematic Study in Parameter Space AI翻译

  摘要：This article considers the consensus of a general class of second-order multiagent systems (MASs) with time delays, where the controller is of the common proportional and derivative (PD) type. All the delay and the controller gains are treated as free parameters in this article, and our objective is to develop a parameter-space approach that has not been reported in the literature. First, we adopt the complete stability analysis w.r.t. delay under a given PD controller for the corresponding ch...

  摘要：Compound matrices have found applications in many fields of science including systems and control theory. In particular, a sufficient condition fork-contraction is that a logarithmic norm (also called matrix measure)of the k-additive compound of the Jacobian is uniformly negative. However, this computation may be difficult to perform analytically and expensive numerically because the k-additive compound of an n x n matrix has dimensions((n)(k))x((n)(k)). This article establishes a duality rela...
• Stability Analysis and Synthesis for Networked Systems With Noisy Sampling Intervals, Random Transmission Delays, and Packet Dropouts AI翻译

  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...
• Sampled-Data Cooperative Output Regulation: An Adaptive Distributed Continuous-Discrete Observer Approach AI翻译
  作者：Zhang, Ying; Su, Youfeng; Cai, He
  作者单位：Fuzhou University; South China University of Technology
  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：This article provides a nonsingular predefined-time terminal sliding mode control scheme for perturbed chains of integrators. Based on the linear delayed feedback technique, a class of nonsingular smooth prescribed-time sliding surfaces with artificial time-delays is constructed, and the control scheme can achieve predefined-time control for perturbed chains of integrators with matched and mismatched disturbances. Especially, for double integrators, an initial-condition-based sufficient condit...
• Recursive Identification of Binary-Valued Systems Under Uniform Persistent Excitations AI翻译
  作者：Ke, Jieming; Wang, Ying; Zhao, Yanlong; Zhang, Ji-Feng

  摘要：This article investigates the online identification problem of binary-valued moving average systems. A stochastic approximation-based algorithm without projections or truncations is proposed. To analyze the convergence property of the algorithm, the distribution tail of the parameter estimate is proved to be exponentially convergent through an auxiliary stochastic process. Under uniform persistent excitations, the almost sure and mean square convergence of the algorithm is obtained. When the s...
• Robust Recursive Regulator for Polytopic Markovian Jump Linear Systems With Random State Delays AI翻译

  摘要：The control problem of dynamic systems that undergo sudden changes and rely on past data is known to be challenging to solve and has received a lot of attention in the past years. Meanwhile, the optimal control theory has been widely used to develop efficient conditions for stability analysis and control synthesis. In this article, we propose a robust regulation strategy for Markovian jump linear systems subject to delayed states and polytopic uncertainties. The time-varying delay belongs to a...

  摘要：This article tackles the predefined-time control problem for nonlinear systems subject to preassigned performance metrics (PPMs) and state constraints. To meet the PPMs and state constraints, the preassigned performance control-based barrier Lyapunov functions are designated to acquire the performance metrics and the satisfaction of state constraints. The proposed control approach combines the predefined-time control with the recursive design of command-filter backstepping to achieve the prese...
• Nonexistence of Upper Bound to Inferencing Level in Decentralized Discrete Event Control AI翻译

  摘要：In the authors' earlier work, the notion of inference-observability was introduced to characterize the existence of decentralized supervisors that perform multilevel inferencing against self-ambiguity and the ambiguities of others to jointly arrive at a correct control decision. When the property of $N$-inference-observability holds, $N$-levels of inferencing are needed. We show in this article that the class of $N$-inference-observable languages increases strictly monotonically as the paramet...
