摘要：This article studies the operation of an electricity market that accounts for participants who bid at a subminute timescale. To that end, we model the market clearing process as a dynamical system, called market dynamics, which is temporally coupled with the grid frequency dynamics and is thus required to guarantee system-wide stability while meeting operational constraints. We characterize participants as price-takers who rationally update their bids to maximize their utility in response to r...

摘要：We study control of constrained linear systems with only partial statistical information about the uncertainty affecting the system dynamics and the sensor measurements. Specifically, given a finite collection of disturbance realizations drawn from a generic distribution, we consider the problem of designing a stabilizing control policy with provable safety and performance guarantees despite the mismatch between the empirical and true distributions. We capture this discrepancy using Wasserstei...

摘要：We investigate decentralized state estimation for a discrete event system in a setting where the information received at a coordinator may be corrupted or tampered by a malicious attacker. Specifically, a system is observed by a set of (local) observation sites (OSs) which occasionally send their recorded sequences of observations to the coordinator that is in charge of estimating the system state. The malfunctions and attacks, referred to as errors in this article, include symbol deletions, i...

摘要：This article proposes a new approach that enables multiagent systems to achieve resilient constrained consensus in the presence of Byzantine attacks, in contrast to existing literature that is only applicable to unconstrained resilient consensus problems. The key enabler for our approach is a new device called a (gamma(i), alpha(i))-Resilient Convex Combination, which allows normal agents in the network to utilize their locally available information to automatically isolate the impact of the B...

摘要：We study the decentralized online regularized linear regression algorithm over random time-varying graphs. At each time step, every node runs an online estimation algorithm consisting of an innovation term processing its own new measurement, a consensus term taking a weighted sum of estimations of its own and its neighbors with additive and multiplicative communication noises and a regularization term preventing over-fitting. It is not required that the regression matrices and graphs satisfy s...

摘要：We propose two new algorithms for solving quadratically constrained quadratic programming (QCQP) problems arising from real-time optimization based control such as model predictive control or interpolating control. The proposed algorithms are based on the Alternating Direction Method of Multipliers (ADMM). ADMM is a powerful tool for solving a wide class of constrained optimization problems. There are two main challenges when applying ADMM: Its performance depends greatly on the efficiency of ...

摘要：This article focuses on estimating the domain of attraction for linear cone-preserving systems subject to saturated linear feedback. The considered system model belongs to a category of control systems whose state trajectories are constrained within proper cones. In terms of cone max norms induced by proper cones, an extended max-separable Lyapunov function is constructed. Furthermore, sufficient criteria are given to show that the level set of this Lyapunov function is contractively invariant...

摘要：In this article, we address the problem of estimating a particular transfer function in a dynamic network, where the unknown noise processes are potentially correlated across the nodes. It is assumed that the noise correlations are affine in essence. We model the spatial correlation between the noise processes of two nodes of the network as a new hidden node that influences the two nodes. To be able to apply the notion of $d$-separation from graph theory, we further manipulate the network by a...

摘要：In this article, we investigate the synthesis problem of edit functions for opacity enforcement in systems modeled as partially observed finite-state automata. For better plausible deniability for the edit functions, in cases where the intruder may learn/know their existence, a synthesis problem for nondeterministic edit functions under a publicly known setting was introduced in the literature, but not yet fully solved. In light of this, we revisit the publicly known edit mechanism by proposin...

摘要：We address the problem of controlling the density of a large ensemble of follower agents by acting on a group of leader agents that interact with them. Using coupled partial integro-differential equations to describe leader and follower density dynamics, we establish feasibility conditions and develop two control architectures ensuring global stability. The first employs feedforward control on the followers' and a feedback on the leaders' density. The second implements a dual feedback loop thr...
