摘要：This technical note studies characterizations and stability criteria for the 2-mode Markovian switched nonlinear systems. A Markovian switched nonlinear system is a switched system where its switching signal is induced by a continuous-time Markov chain. Two random processes-telegraph process and counting process-are defined on the stochastic switching signal. The evolution of the joint probability density functions of the two random processes conditional on the initial values of the switching ...

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：This article presents a method of efficiently computing inner and outer approximations of forward reachable sets for nonlinear control systems with changed dynamics and control authority, given an a priori computed reachable set for the nominal system. The method functions by shrinking or inflating a precomputed reachable set based on prior knowledge of the system's trajectory deviation growth dynamics, depending on whether an inner approximation or outer approximation is desired. These dynami...

摘要：We develop a general matrix pencil-based approach for efficient nonconservative realization of dual dynamic high-gain scaling-based control designs for a class of uncertain feedforward-like nonlinear systems. It is shown that the control design can be cast into a set of matrix pencil-based subproblems capturing the detailed system structure, state dependence structure of uncertain terms, and precise roles of design freedoms in the context of detailed structures of Lyapunov inequalities. The de...

摘要：In this article, we address the problem of attitude estimation for rigid bodies using (possibly time-varying) vector measurements, for which we provide a necessary and sufficient condition of distinguishability. Such a condition is shown to be strictly weaker than those previously used for attitude observer design. Thereafter, we show that even for the single vector case, the resulting condition is sufficient to design almost globally convergent attitude observers, and two explicit designs are...

摘要：The use of game theory for the analysis and design of socio-technological systems has received significant attention as it enables the quantification of the system-level performance while accounting for the presence of individual decision makers. In this context, a popular metric for analyzing the system-level performance is the price of anarchy (PoA), which measures the loss in efficiency caused by distributed decision making. Over the past two decades, significant effort has been devoted to ...

摘要：A new class of nonlinear systems, block logical dynamical systems (BLDSs), is introduced in this note. The existence and uniqueness of solution to BLDSs are first investigated. Then, the topological structure and global stability of BLDSs are analyzed, and a novel criterion is presented to verify the global stability of BLDSs. Finally, the stability of BLDSs is used to study the stability of logical networks subject to time delay. It is shown that the introduction of BLDSs can considerably red...

摘要：In this article, a novel controller design is proposed to solve the finite-time regulation problem of the Heisenberg system, a prototypical nonholonomic system diffeomorphic to the Brockett integrator and many physical systems. Some inherent properties of the Heisenberg system, e.g., the skew-symmetric/diagonal structure, are exploited to obtain a simple-to-tune and bounded control that ensures the finite-time convergence to any point of the state space outside of a zero-measure set. In additi...

摘要：In this work, we consider the problem of event-triggered implementation of control laws designed for the local stabilization of nonlinear systems with center manifolds. We propose event-triggering conditions which are derived from a local input-to-state stability characterization of such systems. The triggering conditions ensure local ultimate boundedness of the trajectories and the existence of a uniform positive lower bound for the inter-event times. The ultimate bound can be made arbitraril...
