摘要：This article addresses a networked control problem for nonlinear plants that are subject to several network-induced issues simultaneously, including multiple independent communication channels, time-varying transmission intervals, sensor schedule protocols, large transmission delays, and updating disorder. A new indicator, the maximum number in updating disorder, is proposed to evaluate the intensity of updating disorder. Then, to describe the complicated relationship between transmission and ...

摘要：In this article, we investigate and derive optimal strategies for the pursuit-evasion problem of two players with damped double integrator dynamics. The pursuer is assumed to have a greater acceleration and attempt to capture the evader as quickly as possible, while the evader wants to avoid or delay the capture. Different from the problems with single integrator dynamics, optimal strategies for such a problem are not intuitive. To solve this problem, we exploit both geometrical methods and di...

摘要：In this article, we introduce novel duality relations that complement the well-known invariant ellipsoids method. These relations yield ellipsoids with newly established geometrical interpretations and connections to linear system norms. The established duality leads to the optimal synthesis results for state-feedback control, filtering, and output-feedback control problems in the presence of bounded disturbances. The proposed output-feedback control solution is demonstrated to be optimal and ...

摘要：In this article, we address the event-triggered consensus problem for single-integrator multiagent systems by introducing a novel nonlinear control protocol. With the proposed consensus protocol, convergence with prescribed transient performance of the closed-loop system can be guaranteed while control execution is triggered by a delicately designed edge-based event-triggering mechanism. The protocol also ensures that no agent exhibits Zeno behavior. Moreover, the method can be extended to the...

摘要：In this article, we consider a cooperative control problem involving a heterogeneous network of dynamically decoupled continuous-time linear plants. The (output-feedback) controllers for each plant may communicate with each other according to a fixed and known transitively closed directed graph. Each transmission incurs a fixed and known time delay. We provide an explicit closed-form expression for the optimal decentralized controller and its associated cost under these communication constrain...

摘要：This article addresses the topic of event-triggered output feedback stabilization of reaction-diffusion partial differential equations (PDEs). The control applies at the boundary while the output is distributed. The control strategy consists of a finite-dimensional controller augmented with an adequate event-triggered mechanism. This event-triggered mechanism dictates the time instants at which the applied control input needs to be updated based on the occurrence of specific events monitored b...

摘要：Stability and safety are crucial in safety-critical control of dynamical systems. The reach-avoid-stay objectives for deterministic dynamical systems can be effectively handled by formal methods as well as Lyapunov methods with soundness and approximate completeness guarantees. However, for continuous-time stochastic dynamical systems, probabilistic reach-avoid-stay problems are viewed as challenging tasks. Motivated by the recent surge of applications in characterizing safety-critical propert...

摘要：The controllability of networked sampled-data systems with zero-order holders on the control and transmission channels is explored, where single- and multirate sampling patterns are considered, respectively. The effects of sampling on the controllability of networked systems are analyzed, with some necessary and/or sufficient controllability conditions derived. Different from the sampling control of single systems, the pathological sampling of node systems could be eliminated by an appropriate...

摘要：This article aims to solve two intricate problems in nonlinear control: 1) the singularity caused by driving the control to infinity at the prescribed time and 2) the stabilization via adaptive event-triggered feedback for a class of uncertain nonlinear systems with asymmetric time-varying output constraints. The difficulty is how to dominate the implicit time in the system and the parameter error multiplied by an adaptive law without breaking the time-varying output constraint. To overcome th...

摘要：This article presents adaptive observers for online state and parameter estimation of a class of nonlinear systems motivated by biophysical models of neuronal circuits. We first present a linear-in-the-parameters design that solves a classical RLS problem. Then, building on this simple design, we present an augmented adaptive observer for models with a nonlinearly parameterized internal dynamics, the parameters of which we interpret as structured uncertainty. We present a convergence and robus...
