Abstract
Disclosed herein are methods and systems for modeling and controlling the disparate components (e.g. generators, storage, propulsors, and power electronics) that comprise an aircraft turbo-electric distributed power (TeDP) system. The resulting control system is hierarchical and interactive. Layer one is the physical electric power system. Layer three is an optimization system that determines set points for system operation. Layer two, in between layer one and layer three, includes nonlinear, fast, dynamic power-electronic controllers that hold the operation of the power system to the desired set points. Communication between these layers ensures feasibility and stability of the controlled operation. Simulations demonstrate that the resulting control system ensures stability and maximum efficiency.
