Overview

This randomized trial demonstrates robust stability and improved trajectory tracking in quadrotor UAVs using a Lyapunov-based backstepping controller.

Key Points

The aim is to develop a robust controller for quadrotor UAVs that addresses control challenges from their nonlinear dynamics and external disturbances.
Developed a Lyapunov-based backstepping (LYP) controller with inner- and outer-loop architecture for position and attitude control.
Compared the LYP controller's performance against PID and FOPID controllers under various scenarios.
Optimized controller gains using Particle Swarm Optimization (PSO).
The LYP controller achieved superior robustness and faster disturbance rejection under nominal and challenging conditions.
Demonstrated improved tracking accuracy with a lower root mean square error (RMSE) compared to PID and FOPID controllers.
