Journal ArticleDOI
Identifying Topology of Low Voltage Distribution Networks Based on Smart Meter Data
TL;DR: The proposed method involves the application of principal component analysis and its graph-theoretic interpretation to infer the steady state network topology from smart meter energy measurements and is demonstrated through simulation on randomly generated networks and on IEEE recognized Roy Billinton distribution test system.
Journal ArticleDOI
Achievable Casimirs and its implications on control of port-Hamiltonian systems
TL;DR: The problem of achievable Dirac structures is now studied for systems with dissipation, in the finite-dimensional, infinite,dimensional and the mixed finite and infinite-dimensional case.
Journal ArticleDOI
Differentiation and Passivity for Control of Brayton–Moser Systems
Krishna Chaitanya Kosaraju,Michele Cucuzzella,Jacquelien M.A. Scherpen,Ramkrishna Pasumarthy +3 more
TL;DR: New passivity properties using a Krasovskii-type Lyapunov function as storage function are presented, where the supply rate is function of the system states, inputs, and their first time derivatives.
Proceedings ArticleDOI
On stability of time delay Hamiltonian systems
TL;DR: The construction of a Lyapunov-Krasovskii (LK) functional based on the Hamiltonian of the port-Hamiltonian system is derived, which derives some sufficient conditions for the system to be asymptotically stable in presence of uncertain delays.
Journal ArticleDOI
Identification and Multivariable Gain-Scheduling Control for Cloud Computing Systems
TL;DR: This paper presents the dynamic modeling and performance control of a Web server hosted on a private cloud with an multiple input multiple output (MIMO) LPV model with performance metrics such as the response time and the throughput and designs a gain scheduled linear quadratic regulator controller for performance guarantees with optimal cost of VMs.
