Software Package on Integrated Nonlinear Dynamic Modeling and Field Oriented Control (FOC) of Permanent Magnet (PM) Motor for High Performance Electromechanical Actuators (EMAs)

摘要

The development of all-electric aircraft is a high priority in the avionics community. Current aircraft use a combination of hydraulic, pneumatic, and electric systems for flight control. However, the expectation for future airplanes is a single, electric system using electromechanical actuators (EMAs). Such a system would reduce the cost to build, operate, and maintain aircraft. It would also make aircraft lighter, more reliable, safer, and more easily reconfigurable, reducing the turnaround for new technology. One of the greatest hurdles to replacing all hydraulic actuators with EMAs is heat generation, a consequence of the absence of cooling hydraulic fluid. Accurately quantifying the heat generated is complicated by the highly transient and localized nature of the power demands of an EMA's motor, an especially significant issue in aircraft. Thus, accurate modeling must be dynamic.
