Machine Learning-Assisted Systems Optimization, Control, and Analytics

Abstract: Recent advances in machine learning, coupled with rapid growth in sensing capabilities and computing power, lead to increasing interest in learning-based techniques for systems optimization, control, and analytics. This presentation will introduce our recent theoretical, algorithmic, and computational results on machine learning-assisted stochastic optimization and control. The first part of the talk focuses on data-driven chance-constrained stochastic optimization. We will begin with the theoretical results of a posteriori probabilistic bounds of convex scenario programs with validation tests that optimize the use of out-of-sample data. Following the scenario program approach, we further present a deep learning-based distributionally robust chance-constrained optimization framework for economic dispatch in electric power systems considering uncertain wind power generation. In the second part of the presentation, we will discuss an online learning-based stochastic model predictive control (MPC) framework with data-driven ambiguity sets. We further establish theoretical guarantees on recursive feasibility and close-loop stability of the proposed stochastic MPC via a safe update scheme. We also develop a data-driven robust MPC framework for the irrigation application, by taking a learning-based approach and considering the dependence of uncertainty probability distributions to construct tailored uncertainty sets from historical forecast error data. The presentation will conclude with a novel deep learning model and quantum-assisted learning algorithm for efficient and effective fault detection and diagnosis in electric power systems and cyber-physical systems.
