A novel efficiency-shifting radial-axial hybrid permanent magnet synchronous motor that can realize two high-efficiency regions at low and high speeds is developed to extend the maximum driving distance and track the reference speed more accurately f

There is a move within the aerospace community to use electromechanical actuators (EMA) in thrust-vector control (TVC) applications. However, shock-wave forces that occur during startup and shutdown of unthrottled TVC rocket engines excite resonance

Within this paper, a method for the real-time simulation of a twelve-pulse full converter is described. The method is based on a finite-difference simulation of the homogeneous state model of the converter with the inputs clamped over an integer mult

This paper demonstrates the simulation of a six-pulse converter within stringent real-time constraints. A clamped-input technique was employed to reduce the computational burden at each time step and to relax the time step constraints associated with
