Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Since the beginning, the development of quadcopters and drones has been strongly influenced by sensors in combination with microprocessors. These flight systems would not be feasible without sensors, because gyros, acceleration sensors and inertial measurement units, for example, are absolutely necessary to make them fly. These are used for axis control. Others, such as the electronic compass, the air pressure sensor or GPS, make control considerably easier for the pilot. Together with sophisticated software, additional sensors such as ultrasonic, infrared or cameras allow additional functions such as automated take-offs and landings, obstacle detection or object tracing. All these sensors and their physical principles are explained in this booklet and their use and possibilities in quadrocopters and drones are discussed. …

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This booklet is intended for everyone who wants to set the control parameters of a quadcopter or who works on his own projects with quadcopters. For anyone who wants to understand why a quadrocopter flies at all, or how it realizes the self-balancing, and how to choose controller parameters so that it reaches a predetermined angle of attack in nick or roll, the reading is recommended.For this purpose, the flight mechanics is first derived in the chapter 'Physical Model'. This leads to the simple model of an axis with two motors. So that a quadcopter can move in one direction, a regulation must be provided which brings it into an angle of attack. This is dealt with in the 'Axis Control' chapter. The drift itself is then either controlled visually by the quadcopter pilot himself or with a superimposed controller that uses GPS as a sensor. This regulation is dealt with in the chapter 'GPS Control'.There are many controller structures for quadcopters in the literature. The one discussed here was deliberately chosen so that it can be implemented with as many flight controllers as possible. In particular, the separation into a subordinate axis control and a superimposed GPS control corresponds to the state of the art in quadcopter controls.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The quadcopters and multicopters used today are driven by brushless motors as standard. In most cases these drive the propellers directly. A gear is used in exceptional cases. This configuration of the drive is essential to the success of the quadcopter in many technical areas and those of everyday life. They can be implemented easily and without complicated mechanics. In addition, the brushless motors including controllers have efficiencies of over 70% and higher, which also makes the drives very efficient. It is therefore to be expected that this type of drive will determine the quadcopters to be developed in the future.In this booklet, the basics for calculating the motor and propeller combinations are worked out. In all cases, these are supplemented with practical calculation examples.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - In this publication, parameter sets for PID controllers are presented, which can be used to control systems with time-delayed stable step responses. These parameter sets minimize the quality criteria in the time domain, IAE, ITAE and ISE. They also take into account the controller output limitation, which is relevant in practice. The parameter sets are scalable with the time constant and the static gain of the system. Therefore they can be used to control all systems with a time delay behavior. …

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This booklet introduces the most important basics of deep learning. It describes the very frequently used method of how a computer can learn using neural networks and training data and apply what it has learned to other questions similar to the training data. Two simple about 'one-pager' examples in Python show how training a neural network with forward and back propagation works and how the trained system can process simple forms of artificial thinking. The two short Python programs 'Learning truth tables' and 'Recognizing a questionnaire' are printed in full and are easy to follow.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Für Single- In, Single- Out Systeme, SISO sind die PID-Regler die mit Abstand am häufigsten eingesetzten Regler. Insbesondere die Regelung von zeitverzögerten Systemen ist herausfordernd. Dazu werden einige heuristische Methoden angewendet, welche man im Zeit und im Frequenzbereich anwenden kann. Das sind beispielsweise diejenigen von Ziegler Nichols, Latzel, oder Chien Hrones und Reswick. Die Parameter, welche damit gefunden wurden ergeben zwar asymptotisch stabile geregelte Systeme. Sie weisen jedoch in den meisten Fällen in der Praxis Einschwingverhalten auf, welche noch eine Nachjustierung erfordern.In dieser Publikation werden Parametersätze für PID Regler vorgestellt, welche für die Regelung von Systemen mit zeitverzögerten stabilen Sprungantworten angewendet werden können. Diese minimieren die gängigen Gütekriterien im Zeitbereich, IAE, ITAE und ISE. Da die Bestimmung der Parametersätze sehr rechenintensiv ist, wurde für deren Berechnung ein Ansatz aus dem Gebiet der künstlichen Intelligenz gewählt.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - For quadcopters there are many names. They are also called quadrocopter, quadricopter, drone, multicopter or simply 'UFO'. This type of model construction is very young. It began early in the new millennium with commercial products for flying camera inspections. One sees quadcopters in all sizes and price ranges on the market. They start with the toy quadcopters, which are small and, despite their low price, often surprisingly robust. In this model division, a similar trend can be observed as with helicopter and airplane models. The smaller and cheaper systems are often built as 'ready to fly', while larger systems are often available as kits. Contents: - Functionality- Ready to fly quadcopters- Components - GPS, photo and film flight- Flight mechanics- Setting the controller- Dimensioning of motors and propellers- Special shapes, tri-, hexa- and octocopters- Initial operation, sources of errors and flight.…
