FLYING LIKE AN ALBATROSS: A JOURNEY INTO THE PERIODIC OPTIMAL CONTROL OF ENERGY SYSTEMS

February 14, 2018 | 1:00 PM | DeWalt Seminar Room, 2164 Martin Hall

Abstract:

This seminar will examine periodic optimal control theory and its application to the optimal control of energy systems.  The seminar is partly motivated by the degree to which optimal control systems can improve the performance, efficiency, and longevity of energy systems such as electrochemical batteries, vehicle-to-grid integration systems, building demand response systems, and large-scale datacenters.  Furthermore, the seminar is inspired by the albatross, a bird that can travel tremendous distances over water with very little energy consumption.  The albatross achieves this by switching periodically between (i) flying at high speeds close to the surface of the ocean, and (ii) gaining potential energy by climbing into the wind.  This “dynamic soaring” pattern exploits the gradient of wind speed with respect to altitude to maximize flight energy efficiency.  Dynamic soaring is just one example of a “proper” periodic optimal control problem: one whose periodic solution is superior to the best achievable steady-state solution.  The seminar will briefly review the literature on periodic optimal control.  The seminar will then examine some of the classical applications of periodic optimal control theory, such as pulse-and-glide driving and the periodic treatment of drug resistance dynamics.  Much of the talk will focus on the application of periodic optimal control to the emerging problems of (i) optimal airborne wind energy harvesting and (ii) battery test trajectory optimization for Fisher parameter identifiability.  The talk will finally conclude with a glimpse of future applications of periodic optimal control, including applications to robotic flight and vehicle connectivity/autonomy.
