Contributors: F. Moore-Clingenpeel*, V. Molazadeh* & N. Sharma*
Event: 2018 IEEE Conference on Decision and Control (CDC) at Miami, FL on December 17-19, 2018
TL;DR:
This work has developed a novel technique based on active subspaces to reduce the dimensionality of the redundant control system and shows that by using this algorithm, synergies can be calculated more quickly than performing dynamic optimization.
