However, the back‐stepping sliding mode control can achieve no overshoot control in the x, z direction, which makes the system more robust. Discarding the control of the yaw angle, the four‐rotor keeps spinning at the same time. Fig. 4 shows the change of the Euler This paper proposes a U-model-based fault-tolerant controller design method in order to ensure the unmanned aerial vehicle (UAV) flight performance when subject to the actuator failures. Depending on the decoupled quadrotor model, this paper presents a sliding mode control method based on U-model in detail and realizes fault-tolerant control for the quadrotor UAV with the stability theory and 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 considered in quadrotor control. The problems these inertial coordinate frame dependent solution have are illustrated by two arbitrary working control solution from recent research papers in chapter 2.

Therefore, numerous papers have dealt with control of the quadro-tor, with many approaches available in that literature that use different control tech-niques. 1.2 Quadrotor Coordinate Frames. For quadrotors there are several coordinate systems that are of interest. In this section we will dene and describe the following coordinate frames: the inertial frame, the vehicle frame, the vehicle-1 frame, the vehicle-2 frame, and the body frame.

Maintainer: Johannes Meyer The main goal for this project was to design a trajectory controller to maneuver the quadrotor through paths that have been derived to minimise snap. Programming and tuning a PID control scheme for a quadrotor to fly. Autonomous and joystick controlled flight were setup. Abstract—We address the problem of cooperative transporta- tion of a cable- suspended payload by multiple quadrotors.

This open-source software contains a complete framework for flying quadrotors based on control algorithms developed by the Robotics and Perception Group.

To address the above problem, MRAC (model reference adaptive control) strategy is used.

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 This brief describes the application of direct and indirect model reference adaptive control to a lightweight low-cost quadrotor unmanned aerial vehicle platform. A baseline trajectory tracking controller is augmented by an adaptive controller. The approach is validated using simulations and flight tested in an indoor test facility.

Control design for a quadrotor is quite similar to a helicopter but simpliﬁed, so that the quadrotor serves as a suitable, more tractable, case study for rotorcraft controls design. Therefore, numerous papers have dealt with control of the quadro-

This section describes the various reference frames and coordinate systems that are used to describe the position of orientation of aircraft, and the transformation between these coordinate systems. It is necessary to use several The purpose is to construct a control algorithm for stable quadrotor ﬂight and explore the use of UAV in a smart home.
