Approximation by Simple Poles -- Part I: Density and Geometric Convergence Rate in Hardy Space
Michael W. Fisher, Gabriela Hug, Florian Dörfler
Optimal linear feedback control design is a valuable but challenging problem due to nonconvexity of the underlying optimization and infinite dimensionality of the Hardy space of st…
Distributed and Constrained Control Design via System Level Synthesis and Dual Consensus ADMM
Panagiotis D. Grontas, Michael W. Fisher, Florian Dörfler
Design of optimal distributed linear feedback controllers to achieve a desired aggregate behavior, while simultaneously satisfying state and input constraints, is a challenging but…
Approximation by Simple Poles -- Part II: System Level Synthesis Beyond Finite Impulse Response
Michael W. Fisher, Gabriela Hug, Florian Dörfler
In Part I, a novel Galerkin-type method for finite dimensional approximations of transfer functions in Hardy space was developed based on approximation by simple poles. In Part II,…
Control Design of Dynamic Virtual Power Plants: An Adaptive Divide-and-Conquer Approach
Verena Häberle, Michael W. Fisher, Eduardo Prieto-Araujo +1
In this paper, we present a novel control approach for dynamic virtual power plants (DVPPs). In particular, we consider a group of heterogeneous distributed energy resources (DERs)…
Hausdorff Continuity of Region of Attraction Boundary Under Parameter Variation with Application to Disturbance Recovery
Michael W. Fisher, Ian A. Hiskens
Consider a parameter dependent vector field on either Euclidean space or a compact Riemannian manifold. Suppose that it possesses a parameter dependent initial condition and a para…
Pressure Fluctuations in Natural Gas Networks caused by Gas-Electric Coupling
Misha Chertkov, Michael Fisher, Scott Backhaus +2
The development of hydraulic fracturing technology has dramatically increased the supply and lowered the cost of natural gas in the United States, driving an expansion of natural g…
Optimal compression in natural gas networks: a geometric programming approach
Sidhant Misra, Michael W. Fisher, Scott Backhaus +3
Natural gas transmission pipelines are complex systems whose flow characteristics are governed by challenging non-linear physical behavior. These pipelines extend over hundreds and…
