Sliding mode control for a quadrotor slung load system

This paper studies the modeling and control of a quadrotor with a suspended load. It is shown that the excessive load swing is the part of the system dynamics, which may degrade the quadrotor control performance. A detailed analysis about the system modeling with the load swing effect is carried out based on Newton-Euler and Euler-Lagrange method. A framework for sliding mode control of the quadrotor slung load system is then developed. The simulation results show the excellent modeling and control performance.
