摘要：This article is concerned with the design of the distributed prescribed-time unknown input observer (DPTUIO) for a class of linear time-invariant systems, which we refer to as the target systems. Results on distributed unknown input observers in literature did not address the convergence time predefinition problem. To achieve fast estimation, this article uses weakly unobservable subspace decomposition and introduces a time-scale transformation technology to develop a novel DPTUIO. This design...

摘要：In this article, we present quasi-interpolation-driven feedback synthesis (QuIFS): an offline feedback synthesis algorithm for explicit nonlinear robust minmax model predictive control (MPC) problems with guaranteed quality of approximation. The underlying technique is driven by a particular type of grid-based quasi-interpolation scheme. The QuIFS algorithm departs drastically from conventional approximation algorithms that are employed in the MPC industry (in particular, it is neither based o...

摘要：This article proposes methods for reachability analysis of nonlinear systems, including those in closed loop with nonlinear controllers such as neural networks. The methods combine hybrid zonotopes, a construct called a state-update set, functional decomposition, and special ordered set approximations to enable linear growth in reachable set memory complexity with time steps and linear scaling in time complexity with the system dimension. Facilitating this combination are new identities for co...

摘要：This article focuses on a class of inclusion problems of maximal monotone operators over directed multiagent networks, where each agent is characterized by a splittable local operator. By integrating the ideas from correction, inexact proximal methods, and push-sum protocol, we proposed a distributed proximal-correction algorithm (referred to as DPCA-& varepsilon;(i)(k)) to solve this inclusion problem of operators, where -& varepsilon;(i)(k) is an agent predetermined accuracy for approximatel...

摘要：In the classical communication setting multiple senders having access to the same source of information and transmitting it over channel(s) to a receiver in general leads to a decrease in estimation error at the receiver as compared with the single sender case. However, if the objectives of the information providers are different from that of the estimator, this might result in interesting strategic interactions and outcomes. In this work, we consider a hierarchical signaling game between mult...

摘要：This article studies the contraction property of time-varying differential-algebraic equation (DAE) systems by embedding them to higher dimension ordinary differential equation (ODE) systems. The first result pertains to the equivalence of the contraction of a DAE system and the uniform global exponential stability of its variational DAE system. Such equivalence inherits the well-known property of contracting ODE systems on a specific manifold. Subsequently, we construct an auxiliary ODE syste...

摘要：This article addresses the exponential regulation problem for uncertain nonlinear impulsive systems with generalized triangular structures. Different from the existing works, the nonlinear growth rates under consideration are allowed to contain unknown constants and state-input-dependent functions, and the impulse effects are allowed to have unknown sizes. This problem has remained unsolved because it exceeds the coverage of common assumptions in impulsive systems. To this end, we propose a no...

摘要：The robust integral of the sign of the error (RISE) control approach results in a powerful continuous controller that yields exponential tracking error convergence despite the presence of time-varying and state-dependent disturbances. However, designing the RISE controller to yield exponential tracking error convergence in the presence of actuator saturation has been an open problem. Although there are existing results that provide a saturation scheme for RISE controllers, these results only g...

摘要：In this article, the problem of remote state estimation is investigated for a class of complex networks with noisy wireless communication channels. The employment of the binary encoding scheme allows for the description of the influence of channel noises as probabilistic bit flips, where the probability of these bit flips is influenced by several factors with the signal-to-noise ratio (SNR) being a crucial one. In engineering practice, the method of adjusting the transmission power for each no...

摘要：The application of distributed model predictive controllers (DMPC) for multiagent systems (MASs) necessitates communication between agents, yet the consequence of communication data rates is typically overlooked. This work focuses on developing stability-guaranteed control methods for MASs with limited data rates. Initially, a distributed optimization algorithm with dynamic quantization is considered for solving the DMPC problem. Due to the limited data rate, the optimization process suffers f...
