Optimization and Differential-Algebraic Equations (Part I of II)
(Invited Minisymposium)

During the last decade, the optimization of systems involving differentialalgebraic equations has become an important research area in applications involving chemical processing, robotics, structural analysis, and aerospace engineering. Frequently, the problem may originate as an optimal control problem where a performance index is to be maximized, or as a prescribed path control problem. Usually, the problems have multiple phases (with possibly unknown junction times of the phases) across which the dynamic equations may change or the inequality path constraints may become active or inactive. Many numerical techniques have evolved for the solution of these problems. Typically, the numerical solution of the continuous problem is determined by a discrete optimization technique, and it is important to understand the connections between the continuous solutions and the discrete solutions. In this minisymposium, the speakers will discuss various optimizationbased approaches to solving these problems, including multiple shooting and direct transcription (or collocation) techniques for solving optimal control problems, parallel methods for largescale systems, and optimization of the mesh.
