An Aircraft Electric Taxiing System (AETS) based on the main landing gear wheel drive for a medium-range aircraft is designed, the simulation analysis is carried out as well.MATLAB/Simulink was used to model AETS. The driving motor model, the mechanical system model and the emission performance evaluation model are constructed. On this basis, the driving capability, stability, energy saving and emission reduction performance are simulated.The simulation results show that the designed system has good driving capability, excellent stability, and obvious energy saving and emission reduction performance.Using this system to drive the target aircraft to taxi on the ground, the maximum speed can reach 4.91 m/s, which basically meets the requirements of taxiing.When the external load fluctuates, its taxiing speed can be adjusted smoothly. Under the same conditions, when the taxiing distance is 1 500 m, using AETS to replace the main engine to drive the aircraft taxiing on the ground can save more than 75% fuel, and reduce the emission of CO, HC, NO
