In this study, the fixed-time SMC method has been proposed for the BLDC motor used in unmanned aerial vehicles (UAV). The proposed method uses the fixed-time sliding surface and fixed-time reaching law as the super-twisting algorithm. Without being affected by the initial conditions, although the gains are chosen the same, it gives better dynamic responses. The stability analysis has been verified also using the Lyapunov method. The superiority of the proposed method has been compared with many existing methods in the literature. Compared to other methods, the overshoot value of the proposed approach is lower than that of existing methods. As a result, the proposed approach has a lower speed error value in the error analyses of all case studies; it achieves a faster rise time value. Moreover, quantitative error analysis shows that the presence of disturbance reduces errors by 51.85% for integral absolute error (IAE), 40.74% for integral square error (ISE), and 3.08% for chattering compared to the best existing method.
