In recent years, brushless DC motors and controllers have begun an unparalleled triumph in model construction and in all technicalfields. This book is intended to show how a brushless motor works.The basic principle is discussed first,...

The multicopters are particularly suitable for dealing with the topics of telemetry or photo flights with UAV, Unmanned Air Vehicles. They allow to float in one place. This also enables a particularly good data transfer to the ground. In...

In order to model a real system, differential equations are usually derived, which are based on physical principles. When modelling a characteristic hysteresis, the mathematical equations are also based on the physics underlying...

Brushless-Motoren und -Regler haben in den vergangenen Jahren überall im Modellbau - und auch in vielen anderen technischen Bereichen - einen unvergleichlichen Siegeszug angetreten. Sie sind inzwischen nicht einfach nur eine Alternative...

In the first years of the new millennium, in the development of radio control technology with 2.4 GHz, a real revolution has taken place. While the frequencies in the MHz range were standard over many years in model construction, a large...

2,4-GHz-Fernsteuerungen Grundlagen und Praxis In den ersten Jahren des neuen Jahrtausends hat bei der Fernsteuertechnologie mit 2,4 GHz eine Revolution stattgefunden. Nachdem die Frequenzen im zweistelligen MHz Bereich über viele Jahre...

Für den Quadrocopter gibt es viele Namen, er wird auch "Quadrotor", "Mikrocop-ter", "Multicopter" oder einfach "Ufo" genannt. Diese Modellbausparte ist sehr jung. Sie nahm ihren Anfang zu Beginn des neuen Jahrtausends mit kommerziel-len...

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...

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...

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...

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...

Die Multicopter eignen sich besonders für die Behandlung der Themen Telemetrie oder auch Fotoflug mit UAV, Unmanned Air Vehicles. Sie erlauben es, an einem Ort zu schweben. Dies ermöglicht auch einen besonders guten Datentransfer zum...
