  摘要：This article is concerned with the stabilization problem for a class of feedforward nonlinear systems via pulsewidth-modulated (PWM) controllers. First, a state observer, which features a dynamic predictor and a jumping update, is designed such that the unavailable full system state can be accurately estimated. With the obtained state estimations, a reference signal is also constructed. Second, a three-level-state-dependent PWM controller is proposed, which switches among three prescribed stat...

  摘要：This work is devoted to stochastic functional differential equations with past-dependent random switching, in which the switching process is allowed to take values in a countable state space. Such processes are rather versatile and arise in a wide variety of applications. A central issue considered in this article is stability. The conditions provided are more general than the existing work. After getting the desired stability results, several applications, including linear systems, linearizat...
• Admission Control of Double-Sided Queues With Multiple Customer Types AI翻译

  摘要：In this technical note, we study a finite double-sided queue with multiple customer types, where two-sided arrivals follow independent Poisson processes. Customers arrive to one side and match with queued customers on the opposite side. A gatekeeper who has complete knowledge of the number of customers decides to accept or reject each arrival. The difference between customer types is defined by the customer's profit to the gatekeeper. Assuming no matching time between the two-sided customers, ...

  摘要：The objective of this article is to study containment control problems for multiagent systems with position constraints and switching topologies. The first contribution is to find conditions under which all agents have the possibility to realize containment control in a distributed manner while the position of each agent is constrained to lie in a specific constraint set in the presence of possible conflicts of the position constraints and the requirement of the convergence into the convex hul...
• Exponential Decay Rate of Linear Port-Hamiltonian Systems: A Multiplier Approach AI翻译
  作者：Mora, Luis A.; Morris, Kirsten
  作者单位：University of Waterloo
  摘要：In this work, the multiplier method is extended to obtain a general lower bound on the exponential decay rate for port-Hamiltonian systems in one space dimension with boundary dissipation. The physical parameters of the system may be spatially varying. It is shown that, under assumptions of boundary or internal dissipation, the system is exponentially stable. This is established through a Lyapunov function defined through a general multiplier function. Furthermore, an explicit bound on the dec...
• Composite Antidisturbance H∞ Control for Hidden Markov Jump Systems With Multi-Sensor Against Replay Attacks AI翻译

  摘要：This article discusses the problem of composite H(infinity )control for hidden Markov jump systems subject to replay attacks. Since it is difficult to obtain the mode information of the system directly in practice, a hidden Markov model is adopted to facilitate subsequent works. The hidden state represents the actual system dynamics that cannot be known exactly, but can be observed by the detector. Considering the multi-disturbance phenomenon, one of which is norm bounded and another is produc...
• State Estimation Over Delayed and Lossy Channels: An Encoder-Decoder Synthesis AI翻译

  摘要：State estimation over a communication channel, in which sensory information of a stochastic source is transmitted in real-time by an encoder to a decoder that estimates the state of the source, is one of the basic problems in networked control systems. In this article, we investigate the performance of state estimation under two primary network imperfections: packet loss and time delay. To that end, we make a causal frequency-distortion tradeoff that is defined between the packet rate and the ...
• On Connections Between Invariant Subspace and Quotient Approaches for Analysis and Control of Boolean Networks AI翻译
  作者：Li, Rui; Zhao, Nan; Zhang, Qi; Chu, Tianguang

  摘要：In this article, we prove new connections between two frameworks for analysis and control of Boolean networks: the invariant subspace framework and the quotient framework. Each method, in different ways, produces a smaller model but preserves enough information about the original network. We make precise the connection between models reduced by the two methods. The results show equivalence between invariant subspace and quotient approaches for wide classes of analysis and control problems.
• Generalization of Filtering Sensitivity Tradeoffs in Continuous- and Discrete-Time Systems: A Simplified Approach AI翻译

  摘要：A simplified analysis is performed on the Bode-type filtering sensitivity tradeoff integrals, which capture the sensitivity characteristics of the estimate and estimation error with respect to the process input or estimated signal in continuous- and discrete-time linear time-invariant filtering systems. Compared with the previous analyses based on complex analysis and Cauchy's residue theorem, the analysis results derived from the simplified method are more explicit, thorough, and require less...
• Optimal Transmission Scheduling Over Multihop Networks: Structural Results and Reinforcement Learning AI翻译

  摘要：This article studies the optimal transmission scheduling for remote state estimation over multihop networks. A smart sensor observes a dynamic system, and sends its local state estimate to a remote estimator (RE). To save energy, multihop networks are deployed to relay data packets from the smart sensor to the RE. The smart sensor needs to decide the hop number communicating with the RE by adjusting its transmission power. To minimize the estimation error and the energy consumption, the transm...
