Book Description :

This design guide was written to capture the author’s practical experience of designing, building and testing multi-rotor drone systems over the past decade. The lack of one single source of useful information meant that the past 10 years has been a steep learning curve, a lot of self-tuition and many trial and error tests. Lessons learnt the hard way are not always the best way to learn. This book will be useful for the amateur drone pilot who wants to build their own system from first principles, as well as the academic researcher investigating novel design concepts and future drone applications.

Book Description :

A hybrid-like (continuous and discrete-event) approach to controlling a small multi-rotor unmanned aerial system (UAS) while landing on a moving platform is described. The landing scheme is based on positioning visual markers on a landing platform in a detectable pattern. After the onboard camera detects the object pattern, the inner control algorithm sends visual-based servo-commands to align the multi-rotor with the targets. This method is less computationally complex as it uses color-based object detection applied to a geometric pattern instead of feature tracking algorithms, and has the advantage of not requiring the distance to the objects to be calculated. The continuous approach accounts for the UAV and the platform rolling/pitching/yawing, which is essential for a real-time landing on a moving target such as a ship. A discrete-event supervisor working in parallel with the inner controller is designed to assist the automatic landing of a multi-rotor UAV on a moving target. This supervisory control strategy allows the pilot and crew to make time-critical decisions when exceptions, such as losing targets from the field of view, occur. The developed supervisor improves the low-level vision-based auto-landing system and high-level human-machine interface. The proposed hybrid-like approach was tested in simulation using a quadcopter model in Virtual Robotics Experimentation Platform (V-REP) working in parallel with Robot Operating System (ROS). Finally, this method was validated in a series of real-time experiments with indoor and outdoor quadcopters landing on both static and moving platforms. The developed prototype system has demonstrated the capability of landing within 25 cm of the desired point of touchdown. This auto-landing system is small (100 x 100 mm), light-weight (100 g), and consumes little power (under 2 W).

Book Description :

For a growing number of flight operations, human piloted aircraft are being replaced by autonomous uncrewed aerial vehicles (UAVs) which can provide equivalent service with drastically reduced operating costs. The UAVs that are deployed in mission critical applications, such as search and rescue, medical deliveries to remote locations, infrastructure inspection, and reconnaissance and surveillance, must be extremely resilient as the loss of a vehicle poses significant threats to financial, security, or personnel interests. In order to rely on uncrewed systems in these mission critical situations, we must have confidence in their ability to perform their duties as reliably as possible. Recent advancements in hardware, software, and control design have increased the reliability of these small inexpensive aircraft. The focus of this dissertation is to further improve multi-rotor reliability in the presence of a broad class of disturbances, while providing a unifying framework that can be extended to multiple applications. The methods we present in this work are based on a feedback linearizing control strategy in which the controller is augmented with an extended high-gain observer. The addition of the extended high-gain observer allows us to overcome the typical drawbacks associated with using a feedback linearization control approach; primarily that we must have an excellent model of the system, and we must know any disturbances that are affecting the system. The extended high-gain observer not only provides estimates of any model uncertainties or external disturbances, but also any unmeasured states for use in output feedback control. This estimation and control strategy enables the multi-rotor to robustly track a trajectory in the presence of a broad class of unmodeled disturbances and without needing an extremely accurate system model. This method forms the base technology applied throughout this dissertation. We extend our estimation and control strategy in a number of ways in the coming chapters. We begin by extending the observer dynamics further to incorporate real-time trajectory estimation for a reference system which may have partially known or completely unknown dynamics, and for which we assume we only have access to the position of the reference system. The observer is then able to provide estimates of all higher-order trajectory terms required for feedforward control, improving transient tracking performance. We further extend this strategy to enable both the detection and classification of a complete actuator failure of a multi-rotor during flight. The identification subsequently enables a control reconfiguration and a recovery from the loss of an actuator to resume flight operations. This extension provides the ability to not only detect and correctly identify a failure, but to discern the failure from other external disturbances affecting the system during flight. Finally, we extend our estimation and control strategy to enable robust trajectory tracking for a novel form of multi-body multi-rotor systems. This type of system consists of a large carrier UAV which suspends a small platform which is itself actuated by a pair of rotors. The platform is equipped with a manipulator which enables long reach aerial manipulation. One advantage of this configuration is the workspace will not be disturbed by downwash from the carrier UAV. Each of these methods are rigorously analyzed to guarantee closed-loop stability and provide insights into the trade-offs that arise during the design process for these control systems utilizing extended high-gain observers.

Book Description :

This text is a thorough treatment of the rapidly growing area of aerial manipulation. It details all the design steps required for the modeling and control of unmanned aerial vehicles (UAV) equipped with robotic manipulators. Starting with the physical basics of rigid-body kinematics, the book gives an in-depth presentation of local and global coordinates, together with the representation of orientation and motion in fixed- and moving-coordinate systems. Coverage of the kinematics and dynamics of unmanned aerial vehicles is developed in a succession of popular UAV configurations for multirotor systems. Such an arrangement, supported by frequent examples and end-of-chapter exercises, leads the reader from simple to more complex UAV configurations. Propulsion-system aerodynamics, essential in UAV design, is analyzed through blade-element and momentum theories, analysis which is followed by a description of drag and ground-aerodynamic effects. The central part of the book is dedicated to aerial-manipulator kinematics, dynamics, and control. Based on foundations laid in the opening chapters, this portion of the book is a structured presentation of Newton–Euler dynamic modeling that results in forward and backward equations in both fixed- and moving-coordinate systems. The Lagrange–Euler approach is applied to expand the model further, providing formalisms to model the variable moment of inertia later used to analyze the dynamics of aerial manipulators in contact with the environment. Using knowledge from sensor data, insights are presented into the ways in which linear, robust, and adaptive control techniques can be applied in aerial manipulation so as to tackle the real-world problems faced by scholars and engineers in the design and implementation of aerial robotics systems. The book is completed by path and trajectory planning with vision-based examples for tracking and manipulation.
