摘要:This article is the third and final component of a three-part effort on observers contracting a Riemannian distance between the state of the system and its estimate. In Part I, we showed that such a contraction property holds if the system dynamics and the Riemannian metric satisfy two key conditions: a differential detectability property and a geodesic monotonicity property. With the former condition being the focus of Part II, in this Part III, we study the latter condition in relationship t...

摘要:This article is concerned with the distributed leader-following fault-tolerant consensus control problem of uncertain nonlinear delayed multiagent systems with hybrid faults including actuator faults and sensor faults. The faults are described as unknown time-varying functions, which can cause uncertain changes in the fault coefficients of sensors and actuators. In this case, we put forward a novel distributed consensus algorithm. First, we transform the consensus problem into the stability on...

摘要:It is practically interesting to achieve global event-triggered control for mismatched uncertain nonlinear systems subject to sensor and actuator faults. In this article, we present a low-conservative solution and consider the output-feedback scenario. The design and analysis innovations include the following: 1) by using a scaling transformation with its gain being online tuned dynamically, we convert the original system with constant coefficients into one with dynamic coefficients, allowing ...

摘要:In this article, the specified-time affine formation maneuver control (AFMC) problem is studied with a leader-follower structure over a directed communication network. First, by means of Pontraygin's maximum principle and motion-planning techniques, a specified-time AFMC algorithm is designed for the second-integrator systems with dynamic leaders, which can lead the followers to achieve the desired affine formation at a specified settling time according to mission requirements and environmenta...

摘要:This article investigates the problem of sensor scheduling for remotely estimating the states of heterogeneous dynamical systems over resource-limited and lossy wireless channels. Considering the low time complexity and high versatility requirements of schedulers deployed on the transport layer, we propose a lightweight scheduler based on an Age of Information function built with the tight scalar upper bound of the remote estimation error. We show that the proposed scheduler is indexable and s...

摘要:This article discusses the Dirac structure and the state-space representation of a class of port-Hamiltonian systems that evolve in discrete time. The characterization of the underlying Dirac structure depends on separating the stored energy associated with the system into two distinct components. Moreover, it is shown that power-preserving interconnection and negative output feedback maintain the port-Hamiltonian structure while increasing the dimension of the Dirac structure. Finally, the pr...

摘要:In a Stackelberg game, a leader commits to a randomized strategy and a follower chooses their best strategy in response. We consider an extension of a standard Stackelberg game, called a discrete-time dynamic Stackelberg game, that has an underlying state space that affects the leader's rewards and available strategies and evolves in a Markovian manner depending on both the leader and follower's selected strategies. Although standard Stackelberg games have been utilized to improve scheduling i...

摘要:This article investigates a preset-time and preset-accuracy human-in-the-loop cluster consensus control approach for nonlinear multi-agent systems (MASs) on a directed graph under stochastic actuation attacks. First, a new preset-time and preset-accuracy Zeno-free event-triggered observer that requires neither each agent to access the human agent information nor the first (n-1) derivatives of the human agent output is designed by using a preset-time and preset-accuracy convergence performance ...

摘要:The synthesis problem of the interconnection of homogeneous linear time-invariant systems such that the frequency response satisfies magnitude constraints is investigated. To this end, the usual synthesis approach of traditional filters, viewed as the interconnection of integrators 1/s, is revisited based on the linear fractional transformation representation and the {x,y,z}-dissipative characterization. This approach, based on convex optimization, consists of two steps: the magnitude synthesi...

摘要:In this note, we propose a framework for the event-based semiglobal practical stabilization of nonlinear continuous-time systems based on limited amount of information. Following an emulation approach, it is required the availability of a convergent state observer and of a global asymptotic stabilizer in continuous time, generally depending on the estimated state and on the measured output. We then introduce time sampling, quantizations on the input, observed state and output signals, and a pe...
