This paper presents a review of the various control strategies that have been conducted to
address and resolve several challenges for a particular category of unmanned aerial …

Random external disturbances/parametric uncertainties and other factors deteriorate the
tracking control performances of the quadrotor unmanned aerial vehicle (QUAV). To achieve …

With the increasing use of quadrotors, the design of flight control systems has become
particularly important. In this paper, a new robust flight control system consisted of an …

So-called robot–object Lagrangian systems consist of a class of nonsmooth underactuated
complementarity Lagrangian systems, with a specific structure: an “object” and a “robot” …

Artificial-delay control is a method in which state and input measurements collected at an
immediate past time instant (ie, artificially delayed) are used to compensate the uncertain …

In this article, we develop a methodology for trajectory tracking control of a vertical takeoff
and landing (VTOL) unmanned aerial vehicle (UAV) in the presence of unknown mass and …

By considering the under-actuated characteristics of the quadcopter suspension
transportation system and the external disturbance, the effective tracking control of the …

In this article, the control problem for the underactuated dynamic system, which consists of a
quadrotor unmanned aerial vehicle and a suspended payload is investigated under the …

Two novel nonlinear control schemes for Unmanned Aerial Vehicles (UAV) carrying a load
and their comparative results are presented in this paper. The goal is to carry the load to a …

In controller design for quadrotors, the drag coefficients, thrust coefficients, and aerodynamic
damping coefficients are usually unmeasurable, and they have to be regarded as uncertain …
