摘要：The optimal consensus control problem of constrained multiagent systems is studied in this article. Considering the transient performance, the final consensus state and constraints simultaneously, the problem is formulated as a constrained nonseparable optimization problem accounting for the control inputs and the final consensus state. A distributes hybrid gradient projection alternating direction method of multipliers is designed to separate the coupled problem to independent subproblems sol...

摘要：In this article, the robust quantized sampled-data tracking control problem of nonlinear systems affected by actuation disturbances and observation errors is studied. In particular, results concerning the robustification and the quantized sampled-data implementation of tracking controllers are provided for nonlinear systems in control-affine form. Inspired by the well-known notion of steepest descent feedbacks, the novel notion of steepest tracking feedback (STF) is introduced and the input-to...

摘要：In this article, we analyze the stability of a linear control system where the plant and controller, both containing direct-feedthrough terms, communicate asynchronously over a network using scheduling protocols. The overall system is modeled as a hybrid dynamical system and sufficient conditions for its closed-loop stability are derived using a new Lyapunov function. Additionally, we define a stability property that is associated with the feedthrough terms and the adopted scheduling protocols...

摘要：This article formulates the optimal steady-state regulation (OSSR) problem. In addition to asymptotic stability and regulation, the problem includes a cost on maintaining steady-state inputs and outputs to controllers contributing to regulation, contrasting with standard optimal steady-state problems that only include a cost on the steady-state inputs and outputs of the plant. Motivated by applications in neuroscience, we develop a two-timescale adaptive control architecture to solve a specifi...

摘要：This article deals with the existence and robust stability of hybrid limit cycles for a class of hybrid systems given by the combination of continuous dynamics on a flow set and discrete dynamics on a jump set. For this purpose, the notion of Zhukovskii stability, typically stated for continuous-time systems, is extended to the hybrid systems. Necessary conditions, particularly, a condition using a forward invariance notion, for existence of hybrid limit cycles are first presented. In addition...

摘要：Asymptotic stability is with no doubts an essential property to be studied for any system. This analysis often becomes very difficult for coupled systems and even harder when different time-scales appear. The singular perturbation method allows to decouple a full system into what are called the reduced-order system and the boundary layer system to get simpler stability conditions for the original system. In the infinite-dimensional setting, we do not have a general result making sure this stra...

摘要：This article proposes a data-driven control framework to regulate an unknown stochastic linear dynamical system to the solution of a stochastic convex optimization problem. Despite the centrality of this problem, most of the available methods critically rely on a precise knowledge of the system dynamics, thus requiring offline system identification. To solve the control problem, we first show that the steady-state gain of the transfer function of a linear system can be computed directly from h...

摘要：Linear complementarity problems provide a powerful framework to model nonsmooth phenomena in dynamical control systems. Mimicking the general strategy that led to the foundation of bifurcation theory in smooth maps, we introduce a novel notion of equivalence between linear complementarity problems that sets the basis for a theory of bifurcations in a large class of nonsmooth maps, including steady-state bifurcations in linear complementarity systems. Our definition leads to constructive algebr...

摘要：Mixed-integer optimal control problems arise in many practical applications combining nonlinear, dynamic, and combinatorial features. To cope with the resulting complexity, several approaches have been suggested in the past. Some of them rely on solving a reformulated and relaxed control problem, referred to as partial outer convexification (POC). Inspired by an efficient algorithm for switching time optimization by Stellato and coworkers, SwitchTimeOpt.jl, we developed an algorithmic approach...

摘要：In this article, the recursive Bayesian estimation problem is investigated for a class of linear discrete-time systems subject to state-dependent packet dropouts. During the transmission to a remote estimator, the data packets carrying the local measurements might be dropped if the system state is located within certain occlusion region, and this gives rise to a nonstationary dropout process relying on real system states. In this scenario, due to the exponential growth of the computational cos...
