| 摘要: |
| An aileron is a crucial control surface for rolling. Any jitter or shaking caused by the aileron mechatronics could have
catastrophic consequences for the aircraft’s stability, maneuverability, safety, and lifespan. This paper presents a robust
solution in the form of a fast flutter suppression digital control logic of edge computing aileron mechatronics (ECAM). We
have effectively eliminated passive and active oscillating response biases by integrating nonlinear functional parameters and
an antiphase hysteresis Schmitt trigger. Our findings demonstrate that self-tuning nonlinear parameters can optimize stability,
robustness, and accuracy. At the same time, the antiphase hysteresis Schmitt trigger effectively rejects flutters without the
need for collaborative navigation and guidance. Our hardware-in-the-loop simulation results confirm that this approach can
eliminate aircraft jitter and shaking while ensuring expected stability and maneuverability. In conclusion, this nonlinear
aileron mechatronics with a Schmitt positive feedback mechanism is a highly effective solution for distributed flight control
and active flutter rejection. |
