As the near space atmospheric environment is complicated and variational, aircraft electric propulsion system parameters and load characteristics of the propeller will be changed, if the control method of electric propulsion system shall not be treated, the system stability and reliability will be affected. A novel double close loops control method with current and speed was presented in this paper, PI control combined with fuzzy adaptive scheme was developed for high-performance robust speed controller, which has the advantages of fuzzy adaptive control and PI control, PI control was developed for the current controller. And the system simulation experiments were accomplished in Matlab/Simulink. The simulation results are illustrated to show that the system works well, has very good static and dynamic performance, strong robustness and self-adaptive ability than PI control.
