Book Description
Parallel hybrid-electric propulsion systems would be beneficial for small unmanned aerial vehicles (UAVs) used for military, homeland security, and disaster monitoring missions involving intelligence, surveillance, or reconnaissance (ISR). The benefits include increased time-on-station and range than electric-powered UAVs and stealth modes not available with gasoline-powered UAVs. A conceptual design of a small UAV with a parallel hybrid-electric propulsion system, an optimization routine for the energy use, the application of a neural network to approximate the optimization results, and simulation results are provided. The two-point conceptual design includes an internal combustion engine sized for cruise and an electric motor and lithium-ion battery pack sized for endurance speed. The flexible optimization routine allows relative importance to be assigned between the use of gasoline, electricity, and recharging. The Cerebellar Model Arithmetic Computer (CMAC) neural network approximates the optimization results and is applied to the control of the parallel hybrid-electric propulsion system. The CMAC controller saves on the required memory compared to a large look-up table by two orders of magnitude. The energy use for the hybrid-electric UAV with the CMAC controller during a one-hour and a three-hour ISR mission is 58% and 27% less, respectively, than for a gasoline-powered UAV.

Book Description
Although many believe that unmanned aerial vehicles or drones are a recent invention, unmanned flight has a rich history that goes all the way back to ancient times. The first systems that can be specified under the modern definition of unmanned aerial vehicles or drones include reconnaissance drones developed and deployed during the Cold War period. Today, such systems have evolved and can have different designs. In the last twenty years, many drones with different aerodynamic characteristics, flight endurance, methods and places of launch and acceptance, and even more diverse purposes have been developed. The achievements of modern science, technique, and technology, especially in the field of microelectronics and control systems, have made it possible to design and manufacture drones that are capable of performing controllable flight in a wide range of altitudes, speeds, and distances while performing complex and diverse tasks with almost the same efficiency as well as manned aircraft. This book provides a comprehensive overview of drone technology and applications with chapters on the detection and classification of drones, issues related to electric unmanned aerial vehicles, integrating drones into educational curricula, and the uses of different types of drones in various situations, among other topics.

Book Description
Hybrid Technologies for Power Generation addresses the topics related to hybrid technologies by coupling conventional thermal engines with novel technologies, including fuel cells, batteries, thermal storage and electrolysis, and reporting on the most recent advances concerning transport and stationary applications. Potential operating schemes of hybrid power generation systems are covered, highlighting possible combinations of technology and guideline selection according to the energy demands of end-users. Going beyond state-of-the-art technological developments for processes, devices and systems, this book discusses the environmental impact and existing hurdles of moving from a single device to new approaches for efficient energy generation, transfer, conversion, high-density storage and consumption. By describing the practical viability of novel devices coupled to conventional thermal devices, this book has a decisive impact in energy system research, supporting those in the energy research and engineering communities. - Covers detailed thermodynamic requirements for multiple smart technologies included in hybrid systems (i.e., FC, electrolysers, supercapacitors, batteries, thermal storage, etc.) - Features fundamental analysis and modeling to optimize the combination of smart technologies with traditional engines - Details protocols for the analysis, operation and requirements of large-scale production

Book Description
HYDROGEN ELECTRICAL VEHICLES Hydrogen electrical vehicles are an essential component of the “Green New Deal” and this book covers cutting-edge technologies designed for fuel-cell-powered cars. The realization of the decision of 28 countries to keep global warming at 2 degrees and below, which is stated in the Paris Agreement, and the achievement of minimizing CO2 emissions, can only be accomplished by establishing a hydrogen ecosystem. A new geopolitical order is envisaged, in which sectors dealing with energy production, distribution, and storage, thus decreasing the carbon footprint, are reconstructed. In short, an economic order with new tax regulations is being created in which the carbon footprint will be followed. This global effort called the “Green Deal” is defined as a new growth strategy aiming at net-zero CO2 emissions. We know that the total share of transportation in CO2 emissions is about 24%. Therefore, efforts for reducing emissions must include utilizing hydrogen in transport. The subjects covered in the book include: An introduction to hydrogen and electrical vehicles; Hydrogen storage and compression systems; Hydrogen propulsion systems for UAVs; Test and evaluation of hydrogen fuel cell vehicles; Hydrogen production and PEM fuel cells for electrical vehicles; The power and durability issues of fuel cell vehicles. Audience The book will attract readers from diverse fields such as chemistry, physics, materials science, engineering, mechanical and chemical engineering, as well as energy-focused engineering and hydrogen generation industry programs that will take advantage of using this comprehensive review of the hydrogen electrical vehicles.

Book Description
This book addresses selected topics in electrical engineering, electronics and mechatronics that have posed serious challenges for both the scientific and engineering communities in recent years. The topics covered range from mathematical models of electrical and electronic components and systems, to simulation tools implemented for their analysis and further developments; and from multidisciplinary optimization, signal processing methods and numerical results, to control and diagnostic techniques. By bridging theory and practice in the modeling, design and optimization of electrical, electromechanical and electronic systems, and by adopting a multidisciplinary perspective, the book provides researchers and practitioners with timely and extensive information on the state of the art in the field — and a source of new, exciting ideas for further developments and collaborations. The book presents selected results of the XIII Scientific Conference on Selected Issues of Electrical Engineering and Electronics (WZEE 2016), held on May 04–08, 2016, in Rzeszów, Poland. The Conference was organized by the Rzeszów Division of Polish Association of Theoretical and Applied Electrical Engineering (PTETiS) in cooperation with the Faculty of Electrical and Computer Engineering of the Rzeszów University of Technology.
