The invention belongs to the technical field of unmanned aerial vehicle flight control, and discloses an unmanned aerial vehicle rapid composite control method and
system based on fuzzy asymptotic. In the aspect of steady-state precision, the method breaks through the inherent limitation that traditional
finite time control can only achieve bounded neighborhood convergence, and the reliability and execution capacity of the
system in a high-precision task are remarkably improved. In the aspect of
transient response, a nonlinear feedback mechanism in a fractional power form is introduced, so that the
system can obtain a super-linear convergence rate in an initial stage or when encountering large-deviation disturbance. In terms of robustness and
realizability, a structure combining low-pass filtering and dynamic error compensation is adopted in the method, and implementation difficulty caused by high-order differential calculation is effectively avoided; meanwhile, parameter perturbation, unmodeled dynamics, external
wind disturbance and the like are estimated and compensated in combination with an adaptive fuzzy system, and the
adaptive capacity and anti-interference performance of the system in a strong-
coupling and nonlinear environment are remarkably enhanced.
