Abstract
This paper proposes a DC link voltage control strategy for electric propulsion aircraft (EPA). This control strategy aims to achieve dynamic load management while ensuring the DC voltage stability through an adaptive V-I droop control. Unlike the conventional V-I droop control where a steady-state voltage deviation cannot be avoided after perturbations, the voltage deviation is eliminated here through the introduction of the real-time current and voltage measured at the DC link. Stability analysis based on the eigenvalue contours is used to improve the reliability of AC/DC systems for the control parameters used in the proposed control. Besides, the stability region and power boundary for the AC/DC systems are characterized, which provides a safety load curve reference for the power control. These analysis results describe the safety operation margin of the proposed control strategy and provide a voltage and power reference to the futuristic design of AC/DC systems for aviation application. The simulation results demonstrate the effectiveness of the proposed control strategy in terms of response time and DC link voltage deviation.
