The analysis and reduced-order modeling of a proposed aerospace electric drive
Abstract
The aerospace industry has expressed increased interest in replacing hydraulic actuators with electromechanical actuators to capitalize on the savings in weight, efficiency, maintenance, and cost. The proposed drive has these qualities but is difficult to analyze because of the high system order, the large separation in time scales between the electrical and mechanical systems, and the considerable harmonic distortion injected into the link by the load converter. In this work, component and an end-to-end reduced-order models are developed to investigate the salient features of this drive. The end-to-end model eliminates the large separation of time scales which facilitates rapid simulation of mechanical dynamics and mechanical control systems. The model is validated for both operating point and transient conditions. In developing the component models, several potential system improvements were discovered and reported on.
