Abstract: To enhance system stability and speed control for a five-phase permanent magnet synchronous motor (5PMSM) in the propulsion of a two-seater all-electric aircraft, this study compares advanced speed control strategies. The strategies evaluated include feedforward-proportional-integral (FPI) and adaptive backstepping sliding mode (ABS) control, systematically analysed against the classical PI controller. These strategies aim to replace the five traditional PI controllers used in field-oriented control (FOC), enhancing control performance quality. The FPI strategy augments the PI controller by incorporating the difference between current and previous control signal components, enabling effective dqxy-axis regulation. The ABS strategy further enhances control robustness by integrating nonlinear backstepping and sliding mode techniques, ensuring better adaptability to system uncertainties and disturbances. This comparative analysis demonstrates the potential of advanced control methods to improve 5PMSM performance in electric aircraft applications, simulation results conducted in MATLAB software to evaluate effectiveness of the proposed control strategies.
