摘要：Network partitioning has gained recent attention as a pathway to enable decentralized operation and control in large-scale systems. This article addresses the interplay between partitioning, observability, and sensor placement (SP) in dynamic networks. The problem, being computationally intractable at scale, is a largely unexplored, open problem in the literature. To that end, this article's objective is designing scalable partitioning of linear systems while maximizing observability metrics o...

摘要：This article highlights an apparent, yet relatively unknown link between algorithm design in optimization theory and controller synthesis in robust control. Specifically, quadratic optimization can be recast as a regulation problem within the framework of H-infinity control. From this vantage point, the optimality of Polyak's fastest heavy-ball algorithm can be ascertained as a solution to a gain-margin optimization problem. The approach is independent of Polyak's original and brilliant argume...

摘要：In this article, we revisit a communication-control co-design problem for a class of two-player stochastic differential games on an infinite horizon. Each player represents two active decision makers, namely, a scheduler and a remote controller, which cooperate to optimize over a global objective while competing with the other player. Each player's scheduler can only intermittently relay state information to its respective controller due to associated cost/constraint to communication. The sche...

摘要：This article addresses robust stability analysis for moving horizon estimation (MHE) in nonlinear systems and proposes new conditions for tuning the MHE cost function parameters. These conditions are directly linked to the MHE window size and the incremental exponential input/output-to-state stability (i-EIOSS) coefficients of the system. Our approach begins by introducing a general constraint equation within the MHE optimization program, combined with a filtering prior prediction technique. T...

摘要：This article proposes a differentially private gradient-tracking-based distributed stochastic optimization algorithm over directed graphs. In particular, privacy noises are incorporated into each agent's state and tracking variable to mitigate information leakage, after which the perturbed states and tracking variables are transmitted to neighbors. We design two novel schemes for the step-sizes and the sampling number within the algorithm. The sampling parameter-controlled subsampling method e...

摘要：For switched systems, it is often crucial to identify which mode is currently activated. To achieve this, one could design specific control inputs, known as discerning controls, that force the system to reveal its active mode through its measured outputs. A system is said to be controlled mode discernible if such an input exists. Controlled mode discernibility for switched systems with unknown inputs has rarely been discussed, but it has important applications in active fault diagnosis. The ob...
