摘要:This article delves into the investigation of a distributed aggregative optimization problem within a network. In this scenario, each agent possesses its own local cost function, which relies not only on the local state variable but also on an aggregated function of state variables from all agents. To expedite the optimization process, we amalgamate the heavy ball and Nesterov's accelerated method with distributed aggregative gradient tracking, resulting in the proposal of two innovative algor...

摘要:This article is concerned with the problem of fault detection, isolation, and compensation for the multiple-input single-output nonlinear systems in the face of actuator failures. It is focused on the cases of possibly simultaneous failures and unknown inherent nonlinear dynamics, which render the existing solutions infeasible. To conquer these challenges, a novel fault-tolerant funnel control approach based on cyclic performance monitoring and switching mode rearrangement is devised. It detec...

摘要:Recent works have approached the data-driven design of dynamic output-feedback controllers for discrete-time linear time-invariant (LTI) systems by constructing nonminimal state vectors composed of past inputs and outputs. Depending on the system's complexity (order n, lag & ell; and number of outputs p), it was observed in several works that such an approach presents significant limitations. In particular, many works require to restrict the class of LTI systems to those satisfying the relatio...

摘要:This article considers the problem of controller synthesis of a fragment of signal temporal logic (STL) specifications for large-scale multiagent systems, where the agents are dynamically coupled and subject to collaborative tasks. A compositional framework based on continuous-time assume-guarantee contracts (AGCs) is developed to break the complex and large synthesis problem into subproblems of manageable sizes. We first show how to formulate the collaborative STL tasks as AGCs by leveraging ...

摘要:While control theory can be pivotal in addressing societal challenges and helping policymakers in shaping our future, control schemes must incorporate elements of social justice to be both up to the task and fair. In turn, this requires the formulation of new constraints and control objectives and their integration into existing or new control design strategies. Devising a formally sound framework to ensure social fairness in control can enable a leap in understanding the implications of justi...

摘要:In this article, we study the problem of resilient consensus for a multiagent network, where some adversarial nodes attempt to prevent consensus of nonfaulty nodes by transmitting faulty values. Our approach is based on that of the so-called mean subsequence reduced (MSR) algorithm with a special emphasis on its use in agents capable to communicate with multihop neighbors. The MSR algorithm provides an effective technique for agents to achieve resilient consensus if the multiagent network sati...

摘要:We analyze the stability of the logit evolutionary dynamics in population games, possibly with multiple heterogeneous populations. For general population games, we prove that, on the one hand, strict Nash equilibria are asymptotically stable under the logit dynamics for low enough noise levels, on the other hand, a globally exponentially stable logit equilibrium exists for sufficiently large noise levels. This suggests the emergence of bifurcations in population games admitting multiple strict...

摘要:Directed networks widely exist in industrial, social, and natural networks, the consensus of which is characterized by the convergence rate. In this article, a quantitative analysis for the inhibitory effect of directed cycles on the consensus of directed network is provided. Specifically, directed cycle necessarily inhibits network consensus when there is at least one node with in-degree of 1 on the cycle, and the more the nodes with in-degree of 1, the greater the inhibition. The inhibition ...

摘要:State estimation for discrete-time linear systems with uniformly quantized measurements is addressed. By exploiting the set-theoretic nature of the information provided by the quantizer, the problem is cast in the set membership estimation setting. Assuming the possibility of suitably tuning the quantizer range and resolution, the optimal design of adaptive quantizers is formulated in terms of the minimization of the radius of information associated to the state estimation problem. The optimal...

摘要:In this article, we propose a model predictive control (MPC) algorithm using sequential convex programming (SCP) to address concave inequality constraints. Based on traditional SCP, we introduce two methods to improve the solution quality and reduce the cost when SCP is stopped early at each time step. First, we analyze multiple explicit representations of a single constraint and propose a method to reduce convexification loss without solving additional nested dual problems. Second, we map the...
