摘要

A large number of constant power loads with negative impedance characteristics are connected to the power supply system of the multi-electric aircraft, which poses great threats to the system stability. In order to ensure the stability and reliability of the multi-electric aircraft power supply system, the negative impedance feature of constant power loads must be overcome. In this paper, a novel backstepping control strategy based on nonlinear disturbance observer is designed for source-side Buck-Boost converter in the DC power supply system of multi-electric aircraft. The average state space model is converted to Brunovsky standard form by feedback linearization method, furthermore, the disturbances and uncertainties of the system are estimated by using the observer technique. Then the estimations are used as feedforward signals to design a novel backstepping controller, which guarantees the stability of the regulated power supply system. Finally, the effectiveness of the control strategy is verified by simulations and experiments.
