A Systematic Review on Control Strategies of Three Stage Generator for More Electric Aircraft Power System

Abstract

Modern aircraft adopt a three-stage generator power system with variable frequency. It is difficult to ensure the dynamic performance of this system because of its complex architecture, and designing a controller for this system is also challenging as well. Therefore, this study reviews and briefly discusses a number of control strategies for three-stage generators used in AC and DC power systems for aircraft applications under a variety of speed and load variations. The performance of different strategies is evaluated based on settling time and percentage overshoot in steady and transient states; their results are summarized in Table I.
