Particle Clustering Machine: A Dynamical System Based Approach
Sambarta Dasgupta, Keivan Ebrahimi, Umesh Vaidya
Identification of the clusters from an unlabeled data set is one of the most important problems in Unsupervised Machine Learning. The state of the art clustering algorithms are bas…
Contingency Analysis of Power Networks : A System Theoretic Approach
Sambarta Dasgupta, Umesh Vaidya
In this work, we have proposed a system theoretic method to compute sensitivities of different lines for contingency analysis in power network. We have formulated the c…
Normally hyperbolic surfaces based finite-time transient stability monitoring of power system dynamics
Sambarta Dasgupta, Umesh Vaidya
In this paper, we develop a methodology for finite time rotor angle stability analysis using the theory of normal hyperbolic surfaces. The proposed method would bring new insights…
Data-Driven Approximation of Transfer Operators: Naturally Structured Dynamic Mode Decomposition
Bowen Huang, Umesh Vaidya
In this paper, we provide a new algorithm for the finite dimensional approximation of the linear transfer Koopman and Perron-Frobenius operator from time series data. We argue that…
On Information Transfer in Control Dynamical Systems
Subhrajit Sinha, Umesh Vaidya
In this paper, we show through examples, how the existing definitions of information transfer, namely directed information and transfer entropy fail to capture true causal interact…
Transfer Operator Based Approach for Optimal Stabilization of Stochastic System
Apurba Kumar Das, Arvind Raghunathan, Umesh Vaidya
In this paper we develop linear transfer Perron Frobenius operator-based approach for optimal stabilization of stochastic nonlinear system. One of the main highlight of the propose…
Fragility of Decentralized Load-Side Frequency Control in Stochastic Environment
Sai Pushpak, Umesh Vaidya
In this paper, we demonstrate the fragility of decentralized load-side frequency algorithms proposed in [1] against stochastic parametric uncertainty in power network model. The st…
