Error Bounds for Compositions of Piecewise Affine Approximations

no code implementations23 Feb 2024 Jonah J. Glunt, Jacob A. Siefert, Andrew F. Thompson, Herschel C. Pangborn

Nonlinear expressions are often approximated by piecewise affine (PWA) functions to simplify analysis or reduce computational costs.

A Set-Based Approach for Robust Control Co-Design

no code implementations18 Oct 2023 Trevor J. Bird, Jacob A. Siefert, Herschel C. Pangborn, Neera Jain

Control Co-Design (CCD) considers the coupled effects of both the plant and control parameters to optimize a system's closed-loop transient performance during the design stage.

A System-Level Energy-Efficient Digital Twin Framework for Runtime Control of Batch Manufacturing Processes

no code implementations18 Sep 2023 Hongliang Li, Herschel C. Pangborn, Ilya Kovalenko

To improve the scheduling and control of batch manufacturing processes, we propose a system-level energy-efficient Digital Twin framework that considers Time-of-Use (TOU) energy pricing for runtime decision-making.

Successor Sets of Discrete-time Nonlinear Systems Using Hybrid Zonotopes

no code implementations18 Oct 2022 Jacob A. Siefert, Trevor J. Bird, Justin P. Koeln, Neera Jain, Herschel C. Pangborn

This paper presents identities for calculating over-approximated successor sets of discrete-time nonlinear systems using hybrid zonotopes.

Hybrid zonotopes: a new set representation for reachability analysis of mixed logical dynamical systems

no code implementations28 Jun 2021 Trevor J. Bird, Herschel C. Pangborn, Neera Jain, Justin P. Koeln

This article presents a new set representation named the hybrid zonotope that is equivalent to the union of $2^N$ constrained zonotopes -- convex polytopes -- through the addition of $N$ binary zonotope factors.

Robust Control Co-Design with Receding-Horizon MPC

no code implementations5 Apr 2021 Austin L. Nash, Herschel C. Pangborn, Neera Jain

Control co-design (CCD) is a technique for improving the closed-loop performance of systems through the coordinated design of both plant parameters and an optimal control policy.
