In order to address climate change and achieve the ambitious goal of net-zero emissions, the concept of all-electric aircraft offers a disruptive technological pathway for the aviation sector. The propulsion system of all-electric aircraft is entirely powered by clean energy sources, such as hydrogen, which plays a key role in facilitating the transition to renewable energy. However, the integration of numerous additional electric devices and drives has significantly increased the complexity and power capacity requirements of the propulsion system. As a result, more constraints are placed on testing its dynamic performance, verifying the control strategy, and managing energy consumption at a system level.
Dehao's research aim is to develop a system-level hardware-in-the-loop (HIL) test bench for the electric propulsion system of all-electric aircraft, providing robust support for optimizing and enhancing its performance against uncertain disturbance. This objective includes addressing communication between various electric devices, developing real-time mathematical models for non-critical components, integrating the cyber and physical environments, and optimizing controllers and operation strategy. The HIL test bench will provide researchers with the capability to acquire more reliable operational characteristics of the propulsion system under realistic conditions. The establishment of HIL test bench is composed of propulsive electric motors, DC power grid, controllers, and other simulated electronics, with real power flowing through it
