Novel nonlinear inductance modeling of permanent magnet motor

Power management has become a significant concern that must be addressed before the realization of an all-electric aircraft. Electromechanical actuators (EMAs) for flight control surfaces are of special concern. They demand high power with highly variable duty cycles and are extremely flight-critical. Dynamic, nonlinear, lumped-element modeling of permanent magnet motors provides the means to simulate with high fidelity and speed the behavior of EMAs over any given mission profile. This paper focuses on a successful technique of dynamic, nonlinear inductance modeling which is at the heart of modeling the whole EMA.
