Quadrotor Unmanned Aerial Vehicle (UAV) is an unstable system, so it needs to be
controlled efficiently and intelligently. Moreover, due to its non-linear, coupled, and under …

Control of aerial robots is a popular research field as applications with different payloads
lead to a variety of flight missions. Quadrotor-type unmanned systems are one such example …

In this article, a discrete-time adaptive fuzzy command filtered backstep** control scheme
is presented for the altitude and attitude control problems of the quadrotor unmanned aerial …

A hexacopter aircraft is a class of helicopter, more specifically of multirotors. The hexacopter
has several characteristics (mechanically simple, vertical takeoff and landing, hovering …

The main purpose of this paper is to integrate fuzzy logic control and sliding mode control
techniques based on backstep** approach to develop a robust fuzzy backstep** sliding …

To overcome nonlinear and 6-DOF (degrees of freedom) under-actuated problems for the
attitude and position of quadrotor UAVs, an adaptive backstep** sliding mode method for …

The problem addressed in the present paper is the design of a controller based on an
evolutionary neural network for autonomous flight in quadrotor systems. The controller's …

In the existing work of tensor product (TP) model transformation, the TP model
transformation-based work on the quadrotor's control system design is scarce, the direct TP …

This paper proposes a hybrid sliding mode control with backstep** with Proportional–
Integral–Derivative sliding surface (PID-SMCBS) flight position control strategy for a …

This paper investigates the possible types of disturbance, viz., aerodynamic factors, sensor
noise, random noise, wind effect, and parametric uncertainty acting on an unmanned aerial …
