Generator overload reduction using smart power management

Weight reduction is a key driver in the aerospace sector. Every kilogram of weight reduction has significant benefits over the aircraft's life cycle. This paper introduces a smart power management technique which is able to reduce the overload on the main aircraft generators. If implemented this would allow the generator size to be reduced at the design stage as no overload capability would be required. The paper first introduces the theoretical and mathematical background of the smart power management controller, utilizing both Linear Temporal Logic and a Finite State Machine. A case study is then used to show the derivation of the controller and demonstrate how smart reconfiguration of power paths (e.g. peak request of power) can reduce the overload on the main aircraft generators.
