Abstract:

By analyzing the electromagnetic launch system of UAVs, the system usually takes constant acceleration launch strategy, the output power increases with the increase of speed, and more batteries are needed to ensure the normal operation of the system, which leads to the larger weight of the energy storage device and its low power density. Through the optimization of the launch strategy for UAV, the constant power limited launch strategy was presented and the controller was designed. Simulation results show that the strategy can effectively reduce the number of batteries in the storage system on the basis of meeting the requirements of the UAV electromagnetic launch process with small velocity perturbation. Compared with before optimization, the power density of the energy storage system increased by 29%.
