摘要：This article studies the saturated stabilization problem of a chain of perturbed integrators subject to measurement errors. Inspired by the technique of nested saturation loops, a key strategy is to employ saturated set-valued maps and a generalized coordinate transformation to overcome the difficulty caused by the measurement errors. It is shown that, with the refined controller design, the closed-loop system is transformed into an interconnection of subsystems, each of which can be rendered ...

摘要：Practical controllers for large-scale systems must be low-order and sparsely communicating, as well as high-performing and robust to uncertainty. H-2-conic design addresses the latter requirements where passivity and H(infinity )methods are inapplicable, but it has yet to address the former. Here, the fixed-order H-2-conic design problem is posed as a series of convergent approximations. The resulting synthesis algorithm uses all controller parameters as explicit design variables, and is guara...

摘要：This technical note presents a specified-time convergent multiagent system for distributed optimization with a time-varying objective function subject to equality constraints. Different from the static optimal solutions to most existing distributed optimization problems, the optimal solutions are time varying due to the time-varying objective function in this problem. A distributed protocol law is designed to ensure all the agents' convergence to feasible and suboptimal solutions within a spec...

摘要：A certain intersection-based architecture for decentralized supervisory control of discrete event systems was proposed in the literature. This existing intersection-based architecture can be regarded as an antipermissive one. In this article, we propose a dual architecture, named the permissive intersection-based architecture, and develop a general architecture by combining the antipermissive and permissive ones. Then, we define a general notion of state-estimator-intersection-based coobservab...

摘要：This article addresses the distributed output feedback leader-following consensus problem for high-order nonlinear multiagent systems (MASs) with time delays and disturbances under the directed network. Using sampled relative outputs to neighbors and the discrete control input, the continuous-discrete time compensator is constructed in each agent to compensate for the consensus errors, where the sampling time instants can be asynchronous and aperiodic without exceeding an explicit upper bound ...

摘要：In this article, we propose a solution to the full-consensus-based formation problem for torque-controlled nonholonomic mobile robots under time-varying communication delays and without velocity measurements. Under the assumptions of static and undirected communication topologies, and smooth and bounded delays, we propose a distributed smooth, time-varying control law which achieves the goal of acquiring a global formation pattern in a common consensus point for both position and orientation. ...

摘要：This study addresses limited attention allocation in a stochastic linear quadratic system with multiplicative noise. Our approach enables strategic resource allocation to enhance noise estimation and improve control decisions. We provide an analytical optimal control and propose a numerical method for optimal attention allocation.

摘要：This article provides a tool for analyzing mechanisms that aim to achieve resilience against stealthy, or undetectable, attacks on cyber-physical systems. We consider attackers who are able to corrupt all of the inputs and outputs of the system. To counter such attackers, a response scheme must be implemented that keeps the attacker from corrupting the inputs and outputs of the system for certain periods of time. To aid in the design of such a response scheme, our tool provides sufficient leng...

摘要：This article is concerned with the problem of nonlinear (stochastic) filter stability for a hidden Markov model (HMM) with white noise observations. A contribution is the variance decay property, which is used to conclude filter stability. For this purpose, a new notion of the Poincar & eacute; inequality (PI) is introduced for the nonlinear filter. PI is related to both the ergodicity of the Markov process and the observability of the HMM. The proofs are based upon a recently discovered minim...

摘要：This study proposes a design technique that solves a robust output regulation problem for a class of nonlinear systems subject to unknown control direction. Nussbaum function techniques are commonly used tools to investigate output regulation problems for various systems subject to unknown control direction. They often lead to large overshoots when the initial estimates of the control direction are wrong. In this study, an extremum-seeking control approach is proposed to overcome the need for ...
