Grouping of $N-1$ Contingencies for Controller Synthesis: A Study for Power Line Failures

no code implementations11 Apr 2024 Neelay Junnarkar, Emily Jensen, Xiaofan Wu, Suat Gumussoy, Murat Arcak

The problem of maintaining power system stability and performance after the failure of any single line in a power system (an "N-1 contingency") is investigated.

Fast Assignment in Asset-Guarding Engagements using Function Approximation

no code implementations11 Apr 2024 Neelay Junnarkar, Emmanuel Sin, Peter Seiler, Douglas Philbrick, Murat Arcak

This subproblem is computationally intensive and hence the computational cost of the assignment is dominated by the construction of the cost matrix.

Synthesizing Neural Network Controllers with Closed-Loop Dissipativity Guarantees

1 code implementation10 Apr 2024 Neelay Junnarkar, Murat Arcak, Peter Seiler

Finally, this convex condition is used in a projection-based training method to synthesize neural network controllers with dissipativity guarantees.

Certifying Stability and Performance of Uncertain Differential-Algebraic Systems: A Dissipativity Framework

no code implementations16 Aug 2023 Emily Jensen, Neelay Junnarkar, Murat Arcak, Xiaofan Wu, Suat Gumussoy

This paper presents a novel framework for characterizing dissipativity of uncertain dynamical systems subject to algebraic constraints.

Synthesis of Stabilizing Recurrent Equilibrium Network Controllers

1 code implementation31 Mar 2022 Neelay Junnarkar, He Yin, Fangda Gu, Murat Arcak, Peter Seiler

We propose a parameterization of a nonlinear dynamic controller based on the recurrent equilibrium network, a generalization of the recurrent neural network.
