This paper addresses the trajectory tracking control problem for a quadrotor suspended load
system without load's linear velocity measurement and cable length information. Firstly, the …

Quadrotors play a significant role in our lives and are transforming our lives. Transporting
cable-suspended loads is an unavoidable quadrotor application trend and a hot research …

We investigate the trajectory tracking problem of a quadrotor-slung-load system with
unknown load mass in the presence of pre-specified performance specifications imposed on …

To meet the realistic demands of autonomous transportation for quadrotor suspended-
payload systems, it is necessary to investigate load trajectory tracking control using only …

This paper is concerned with the motion control for a quadrotor with a cable-suspended load
(QCSL). A fixed-time control strategy is presented to improve the transient response and …

In this paper, we design an optimal control system for a quadrotor to carry a cable-
suspended load flying through a window. As the window is narrower than the length of the …

The safety of the quadrotor transport system (QTS) is always threatened by the suspension
load swing under the fuselage during flight. At the same time, the QTS is affected by …

This paper focuses on the disturbance attenuation control of the quadrotor suspended
payload system with unknown payload mass. Since the quadrotor transportation system is …

This paper presents a geometric finite-time inner-outer loop control strategy for slung
payload transportation using a quadrotor. The underactuated nature of the quadrotor in …

Different from the quadrotor suspended payload system with fixed length cable, the system
with variable length cable can load and unload cargoes more efficiently under many …
