摘要：This article addresses the problem of distributed fixed-time optimization for heterogeneous second-order nonlinear multiagent systems with local time-varying cost functions. The objective is to cooperatively minimize a convex global time-varying cost function formed by a sum of local time-varying cost functions in a fixed time, where each local cost function is not necessarily required to be convex. A state-feedback distributed fixed-time optimization controller with an estimator-based distrib...

摘要：One of the main problems in sparse representation in order to achieve accurate parameter estimation is the potentially large correlation between the regressors. The maximum absolute value of this correlation is called mutual coherence. The inverse of the mutual coherence controls approximately the number of nonzero parameters that can be recovered exactly from noise-free observations. In system identification, the observations are constructed from time-series data, which leads to that the colu...

摘要：In this article, we investigate a distributed constrained optimal formation matching problem for a large-scale multiagent system. A distributed formation matching algorithm for a large-scale multiagent system (DFMA-LSMAS) is proposed. The algorithm employs a distributed continuous-time strategy to deal with a minimal weight bipartite graph matching problem for the optimal matching relationship between each agent and each hole in the formation configuration. It prevents a centralized structure ...

摘要：This article aims to study the stability properties of consensus-based distributed state estimation (DSE) in the presence of denial-of-service (DoS) attacks. Specifically, we adopt a model that describes DoS in terms of its average frequency and duration. We focus on a family of DSE algorithms enjoying stability properties in the ideal case of no attacks, and prove that such properties are preserved under DoS provided that appropriate conditions are satisfied, with specific emphasis on the rel...

摘要：This article addresses the safe stabilization problem of stochastic nonlinear time-delay systems. Based on the Krasovskii approach, we first propose a stochastic control Lyapunov-Krasovskii functional to guarantee the stabilization objective and a stochastic control barrier-Krasovskii functional to ensure the safety objective. Both functionals are developed, respectively, for each control objectives for the first time. Since the optimization problem is not easy to be resolved for stochastic ti...

摘要：This note studies stability of event-triggered control systems with the event-triggered control algorithm proposed in (Zhang et al., 2022). We construct a novel Halanay-type inequality, which is used to show that sufficient conditions of the main results in (Zhang et al., 2022) ensure stability of the event-triggered control systems that was missing in (Zhang et al., 2022). It is also shown that a positive parameter in the proposed event-triggering condition in (Zhang et al., 2022) can be free...

摘要：This article deals with the embedding framework of Markov decision processes (MDPs) with discrete state and action space to find optimal actions. The optimal control problem of MDPs can be efficiently tackled by restructuring the same into an equivalent linearly-solvable Markov decision processes (LMDPs) through the method called embedding. However, state costs under the embedding may not exactly match the original costs and even assume unrealistic values. In this work, we derive a constructiv...

摘要：A nonholonomic robot of a Dubins-vehicle type moves in a changing resistant medium, like water or air. The objective is to exhibit the extension of a spatial phenomenon (e.g., a critically contaminated area) related to a dynamic environmental field (e.g., a distribution of the contaminant concentration). Specifically, the robot should arrive at a certain level set of the field and repeatedly sweep it afterward. The field data come exclusively from online and pointwise measurements of the field...

摘要：Safe control of constrained uncertain linear systems under aleatory uncertainty is considered. Aleatory uncertainty characterizes random noises and is modeled by a probability distribution function (pdf). Data-based probabilistic safe controllers are designed for the cases where the noise pdf is 1) zero-mean Gaussian with a known covariance, 2) zero-mean Gaussian with an uncertain covariance, and 3) zero-mean non-Gaussian with an unknown distribution. Easy-to-check-model-based conditions for g...

摘要：This technical note proposes a novel asynchronous control approach for discrete-time piecewise-affine (PWA) systems with logarithmic quantization of both multiple inputs and multiple state measurements. Since the actual system state and the quantized state may not always be in the same operating region due to quantization-induced uncertainties, the operating modes of the PWA system and the controller that depends on the quantized states may be asynchronous. Aiming at reducing the computational...
