This paper proposes a robust DOB-based Adaptive NTSMC for Quad-tiltrotor eVTOLs. By integrating active disturbance rejection with adaptive gain tuning, the method effectively minimizes chattering and compensates for wind gusts and actuator faults. Simulations demonstrate a 79% tracking improvement over PID, ensuring high reliability for safe Urban Air Mobility operations
