Constrained Reinforcement Learning via Dissipative Saddle Flow Dynamics
Tianqi Zheng, Pengcheng You, Enrique Mallada
In constrained reinforcement learning (C-RL), an agent seeks to learn from the environment a policy that maximizes the expected cumulative reward while satisfying minimum requireme…
Spectral clustering and model reduction for weakly-connected coherent network systems
Hancheng Min, Enrique Mallada
We propose a novel model-reduction methodology for large-scale dynamic networks with tightly-connected components. First, the coherent groups are identified by a spectral clusterin…
Closed-Form Minkowski Sum Approximations for Efficient Optimization-Based Collision Avoidance
James Guthrie, Marin Kobilarov, Enrique Mallada
Motion planning methods for autonomous systems based on nonlinear programming offer great flexibility in incorporating various dynamics, objectives, and constraints. One limitation…
A Market Mechanism for Truthful Bidding with Energy Storage
Rajni Kant Bansal, Pengcheng You, Dennice F. Gayme +1
This paper proposes a market mechanism for multi-interval electricity markets with generator and storage participants. Drawing ideas from supply function bidding, we introduce a no…
Inner Approximations of the Positive-Semidefinite Cone via Grassmannian Packings
Tianqi Zheng, James Guthrie, Enrique Mallada
We investigate the problem of finding inner ap-proximations of positive semidefinite (PSD) cones. We developa novel decomposition framework of the PSD cone by meansof conical combi…
Voltage Collapse Stabilization in Star DC Networks
Charalampos Avraam, Enrique Mallada
Voltage collapse is a type of blackout-inducing dynamic instability that occurs when power demand exceeds the maximum power that can be transferred through a network. The tradition…
