Download or read book Discrete time sliding mode control strategies applied to a multiphase brushless DC machine written by Godoi Dias, Milena Sabrina and published by kassel university press GmbH. This book was released on 2017 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, environmental issues motivates the replacement of mechanical, hydraulic and pneumatic system by electrical system in the transport sector aiming to reduce emissions generated by burning of fossil fuels in vehicles. The electrical system must ensure high electrical efficiency and should not exceed the weight of the substituted components. To attend these high performance requirements a fault-tolerant multiphase brushless DC machine was chosen for this research. The present work introduces a six-phase 600W brushless DC machine with 8 poles. The main challenge for the control issues of this machine is the mutual magnetic coupling between the phases due to the wave winding machine configuration. In this context, theoretical and practical investigations of different current control strategies based on the sliding mode control approach applied to the six-phase brushless DC machine are presented.

Download or read book Multiphase Permanent Magnet Machines written by Kai Wang and published by Wiley-IEEE Press. This book was released on 2024-02-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adoption of advanced technical solutions to match the requirements of energy efficiency is becoming increasingly essential, promoting a gradual transformation in the field of mechanical actuators and shifting the attention to more electric and efficient systems. The main driving force is the need for new solutions in specific application areas such as railway traction, electric and hybrid vehicle applications, ‘more-electric’ aircraft, electric ship propulsion, and general high-power applications. Multi-phase motor drives are gaining a growing interest because they permit a boost in torque and power density, allowing the design of very compact high efficiency drives with positive reliability outcomes. Traditional solutions for electric drive/generation systems, based on three-phase machinery, are not necessarily the best solutions, however. Moreover, since the electric machine is either typically decoupled from the mains, or the actual power system is an autonomous one, the number of phases of the machine does not have to be limited to only three. The resultant ‘multiphase machines’ offer numerous potential advantages over their three-phase counterparts. This book aims at presenting the new research results concerning multiphase machines and drives, AC multiphase power converters and their applications, as related to ‘more-electric’ transport.

Book excerpt: Power electronics technology is still an emerging technology, and it has found its way into many applications, from renewable energy generation (i.e., wind power and solar power) to electrical vehicles (EVs), biomedical devices, and small appliances, such as laptop chargers. In the near future, electrical energy will be provided and handled by power electronics and consumed through power electronics; this not only will intensify the role of power electronics technology in power conversion processes, but also implies that power systems are undergoing a paradigm shift, from centralized distribution to distributed generation. Today, more than 1000 GW of renewable energy generation sources (photovoltaic (PV) and wind) have been installed, all of which are handled by power electronics technology. The main aim of this book is to highlight and address recent breakthroughs in the range of emerging applications in power electronics and in harmonic and electromagnetic interference (EMI) issues at device and system levels as discussed in ‎robust and reliable power electronics technologies, including fault prognosis and diagnosis technique stability of grid-connected converters and ‎smart control of power electronics in devices, microgrids, and at system levels.

Download or read book Autonomous Control of Unmanned Aerial Vehicles written by Victor Becerra and published by MDPI. This book was released on 2019-06-24 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance.

Book excerpt: With countless electric motors being used in daily life, in everything from transportation and medical treatment to military operation and communication, unexpected failures can lead to the loss of valuable human life or a costly standstill in industry. To prevent this, it is important to precisely detect or continuously monitor the working condition of a motor.

It also supplies a solid foundation in the fundamentals of fault cause and effect. Combines Theoretical Analysis and Practical Application Written by experts in electrical engineering, the book approaches the fault diagnosis of electrical motors through the process of theoretical analysis and practical application. It begins by explaining how to analyze the fundamentals of machine failure using the winding functions method, the magnetic equivalent circuit method, and finite element analysis. It then examines how to implement fault diagnosis using techniques such as the motor current signature analysis (MCSA) method, frequency domain method, model-based techniques, and a pattern recognition scheme. Emphasizing the MCSA implementation method, the authors discuss robust signal processing techniques and the implementation of reference-frame-theory-based fault diagnosis for hybrid vehicles.
