TL;DR: In this article, the authors proposed a robust output regulation for a set of quad-rotors forming a geometric pattern, which is composed of cascaded continuous sliding-modes controllers providing uniform finite-time stability and uniform exponential stability for the corresponding quad-Rotors positions.
Abstract: This paper deals with the problem of robust output regulation for a set of Quad-Rotors forming a geometric pattern. The proposed control strategy is based on sliding- modes techniques, and it is able to robustly regulate the corresponding Quad-Rotors positions and angles in the presence of some class of disturbances acting on the Quad-Rotors. The proposed regulation is composed by cascaded continuous sliding-modes controllers providing uniform finite-time stability and uniform exponential stability for the corresponding Quad-Rotors positions. Simulation results illustrate the feasibility of the proposed strategy.

TL;DR: The proposed control strategy provides uniform finite-time stability and uniform exponential stability for the corresponding tracking and formation errors and is composed of cascaded continuous sliding-modes controllers (SMCs).
Abstract: In this paper the problem of motion coordination for a multi-agent system composed of a group of Quad-Rotors, under the leader-follower scheme, is addressed The proposed control strategy is considered as a decentralized scheme and is composed of cascaded continuous sliding-modes controllers (SMCs) By means of this approach, the Quad-Rotors are able to robustly form a geometric pattern in order to track a desired trajectory despite the presence of bounded unknown inputs The proposed control strategy provides uniform finite-time stability and uniform exponential stability for the corresponding tracking and formation errors Numerical simulations illustrate the performance of the proposed control strategy

TL;DR: The results of two nonlinear control techniques applied to an autonomous micro helicopter called Quadrotor are presented, a backstepping and a sliding-mode techniques.
Abstract: The latest technological progress in sensors, actuators and energy storage devices enables the developments of miniature VTOL systems. In this paper we present the results of two nonlinear control techniques applied to an autonomous micro helicopter called Quadrotor. A backstepping and a sliding-mode techniques. We performed various simulations in open and closed loop and implemented several experiments on the test-bench to validate the control laws. Finally, we discuss the results of each approach. These developments are part of the OS4 project in our lab.

TL;DR: In this article, a new approach to control synthesis for robust robot operations in unstructured environments is presented, where the notion of terminal convergence is introduced and control laws based upon a new class of sliding modes, denoted terminal sliders, are developed.
Abstract: Many robotic systems would, in the future, be required to operate in environments that are highly unstructured and active, i.e., possessing means of self-actuation. Although a significant volume of results exist in model-based, robust and adaptive control literature, general issues pertinent to the performance of such control systems remain unresolved, e.g., feasibility of implementing high gain switches for control robustness. It is also pointed out that in certain applications, control switching can be very detrimental to the overall system. The primary focus of this paper is development of a new approach to control synthesis for robust robot operations in unstructured environments. To enhance control performance with full model information, we introduce the notion of terminal convergence, and develop control laws based upon a new class of sliding modes, denoted terminal sliders

TL;DR: A method to measure translational speed as well as the UAV 3D position in a local frame and the performance of three control techniques: Nested Saturations, Backstepping and Sliding Modes is presented.
Abstract: In this paper, we present a comparison of three control techniques: Nested Saturations, Backstepping and Sliding Modes. The control objective consists of obtaining the best control strategy to stabilize the position of a quad-rotor when using visual feedback. We propose a method to measure translational speed as well as the UAV 3D position in a local frame. The selected controllers were implemented and tested in real-time experiments. The obtained results demonstrate the performance of such methodologies applied to the quad-rotor system.
