DISTURBANCE-OBSERVER-BASED FIXED-TIME BACKSTEPPING CONTROL FOR QUADROTORS WITH INPUT SATURATION AND ACTUATOR FAILURE

Disturbance-Observer-Based Fixed-Time Backstepping Control for Quadrotors with Input Saturation and Actuator Failure

This paper investigates Jeans the fixed-time tracking control problem of an unmanned aerial vehicle (UAV) considering the disturbance, input saturation, and actuator failure.According to the hierarchical control principle, the UAV dynamics are decomposed into a translational and rotational loop to accommodate the controller design.A novel nonsingul
