Attitude Control of Variable Exponential Fixed-Time QUAV Based on State Dependent Variables
摘要
This paper investigates a class of robust fixed-time stabilization problems, and applies them to attitude control of quadcopter unmanned aerial vehicle (QUAV). Firstly, the stabilization result of the robust fixed-time stability for the first-order system is given using variable exponential coefficients. Then, using sliding mode method, it is extended to second-order systems and applied to attitude control of QUAV. In the end, we demonstrate the validity of the proposed algorithm through well-designed numerical simulations.
