Abstract
Hydrogen/battery hybrid UAV flights present unique challenges to the adaptability of energy management strategy (EMS) due to dynamic operating conditions (altitude, temperature, humidity, etc.) and diverse flight modes (takeoff, cruising, maneuvering, etc.). In this paper, a novel multi-mode energy management strategy is proposed. First, inspired by the variational Bayesian approach, a noise-adaptive parameter identification method is introduced to monitor the fuel cell characteristics in-flight. The identification results provide an online reference for energy management. Subsequently, a case recognition logic categorizes the flight mode into cruising and non-cruising based on flight power variation. An online rule-based method is deployed for the non-cruising case to prioritize system response, and a novel equivalent consumption minimization strategy (ECMS) is used to maximize system endurance during cruising. Extensive ground tests are conducted with a fuel cell in a constant temperature and humidity chamber, and a flight test is carried out on a self-developed 3 kW fuel cell/battery hybrid UAV. Experimental results show that the proposed method outperforms classic EMSs in terms of system efficiency and reduced system stress. © 2024 IEEE.
