Robust FO Adaptive Nonsingular FTSMC for Uncertain QUAV Under Random Gaussian Disturbances

One of the suitable control schemes for the QUAV system is nonsingular fast terminal SMC (NFTSMC). Combined NFTSMC and FO, robustness against the disturbances, fast speed, singularity avoidance, fast convergence due to the existence of the fractional integral and derivative in the sliding manifolds, can be obtained. In addition, the use of the adaptive law with FONFTSMC, the upper bounds of the disturbances are coped.
