Sliding Mode-Based Control of a UAV Quadrotor for Suppressing the Cable-Suspended Payload Vibration

الملخص EN

This paper addresses the problem of damping vibrations of a cable-suspended payload during positioning of the quadrotor.

A nonlinear model is derived for the coupled quadrotor-pendulum system in the X-Z plane using Euler–Lagrange formulation.

Sliding mode control (SMC) is used for horizontal positioning and payload vibration damping, while a feedback linearizing controller is used for both altitude and attitude control.

The SMC surface parameters are determined by placing the eigenvalues of the linearized system at a desired position.

The simulation results show the effectiveness of the proposed control method in minimizing payload vibration by comparing it with a partial feedback linearizing controller and a ZVDD input shaper.
