Stability Certificates for Receding Horizon Games

no code implementations18 Apr 2024 Sophie Hall, Dominic Liao-McPherson, Giuseppe Belgioioso, Florian Dörfler

Game-theoretic MPC (or Receding Horizon Games) is an emerging control methodology for multi-agent systems that generates control actions by solving a dynamic game with coupling constraints in a receding-horizon fashion.

Additive manufacturing processes are flexible and efficient technologies for producing complex geometries.

Sequential Quadratic Programming-based Iterative Learning Control for Nonlinear Systems

no code implementations24 Jul 2023 Samuel Balula, Efe C. Balta, Dominic Liao-McPherson, Alisa Rupenyan, John Lygeros

We present simulations to illustrate the performance of the proposed method for linear and nonlinear dynamics models.

Stochastic Wasserstein Gradient Flows using Streaming Data with an Application in Predictive Maintenance

no code implementations29 Jan 2023 Nicolas Lanzetti, Efe C. Balta, Dominic Liao-McPherson, Florian Dörfler

Since estimation problems can be posed as optimization problems in the probability space, we devise a stochastic projected Wasserstein gradient flow that keeps track of the belief of the estimated quantity and can consume samples from online data.

Receding Horizon Games with Coupling Constraints for Demand-Side Management

no code implementations3 Jun 2022 Sophie Hall, Giuseppe Belgioioso, Dominic Liao-McPherson, Florian Dörfler

Distributed energy storage and flexible loads are essential tools for ensuring stable and robust operation of the power grid in spite of the challenges arising from the integration of volatile renewable energy generation and increasing peak loads due to widespread electrification.

Data-driven Reference Trajectory Optimization for Precision Motion Systems

no code implementations31 May 2022 Samuel Balula, Dominic Liao-McPherson, Alisa Rupenyan, John Lygeros

We propose a data-driven optimization-based pre-compensation method to improve the contour tracking performance of precision motion stages by modifying the reference trajectory and without modifying any built-in low-level controllers.

On Robustness in Optimization-Based Constrained Iterative Learning Control

no code implementations10 Mar 2022 Dominic Liao-McPherson, Efe C. Balta, Alisa Rupenyan, John Lygeros

Iterative learning control (ILC) is a control strategy for repetitive tasks wherein information from previous runs is leveraged to improve future performance.

In-layer Thermal Control of a Multi-layer Selective Laser Melting Process

no code implementations1 Nov 2021 Dominic Liao-McPherson, Efe C. Balta, Ryan Wüest, Alisa Rupenyan, John Lygeros

Selective Laser Melting (SLM) is an additive manufacturing technology that builds three dimensional parts by melting layers of metal powder together with a laser that traces out a desired geometry.

Cross-layer Design for Real-Time Grid Operation: Estimation, Optimization and Power Flow

no code implementations28 Sep 2021 Miguel Picallo, Dominic Liao-McPherson, Saverio Bolognani, Florian Dörfler

In this paper, we propose a combined Online Feedback Optimization (OFO) and dynamic estimation approach for a real-time power grid operation under time-varying conditions.

FBstab: A proximally stabilized semismooth algorithm for convex quadratic programming

2 code implementations13 Jan 2019 Dominic Liao-McPherson, Ilya Kolmanovsky

This paper introduces the proximally stabilized Fischer-Burmeister method (FBstab); a new algorithm for convex quadratic programming which synergistically combines the proximal point algorithm with a semismooth Newton-type method.
