Fractional-Order Design: Devices, Circuits, and Systems introduces applications from the design perspective so that the reader can learn about, and get ready to, design these applications. The book also includes the different techniques employed to comprehensively and straightforwardly design fractional-order systems/devices. Furthermore, a lot of mathematics is available in the literature for solving the fractional-order calculus for system application. However, a small portion is employed in the design of fractional-order systems. This book introduces the mathematics that has been employed explicitly for fractional-order systems.

Electronic oscillators, which generate sinusoidal waveforms without any input signal, are one of the most widely used active devices. They are used in several areas of science and technology; some potential applications of sinusoidal oscillators are wired and wireless communication systems, navigation systems, radar, and biomedical equipment. Nowadays the concept of fractional calculus is being utilized in the design and realization of various signal processing systems such as integrators, differentiators, filters, and oscillators. This mathematical concept provides some additional degree of freedom and flexibility in the designed system. For example, the phases of the oscillatory waveforms cannot be controlled independently for the conventional designs, whereas it is possible to control the phases by using the fractional calculus approach.

The increasing use of electronically powered and controllable systems in the industrial sector, driven by improved performance, has led to a proliferation of static converters. Today, the research on electronic power converters for the control and command of AC or DC electric motors is constantly increasing. The use of DC or AC electric motors is constantly increasing in the industrial sector thanks to the development of control techniques for pulse-width modulation converters. The production of electrical energy and its transformation into mechanical energy are the basis of the industrial structure in the world. This transformation is possible thanks to AC and DC electric motors. Despite the increasing use and great rivalry with AC motors, which, as three-phase motors, are also part of electric motors, DC motors still play a very important role today. They are often used in industrial applications, because of their properties – in particular the possibility that they offer to adjust their extremely variable torque and speed precisely. This is the case, for example, with the PMA series servo actuators from Harmonic Drive AG, which consist of a high dynamic current motor and a permanent magnet generator reduction mini-cartridge with incremental encoder. They are ideal for applications in the semiconductor industry, medical technology, and measurement and testing machines.

Students and scholars who wants to quickly understand the field of fractional-order systems and contribute to its different domains and applications will find this book a welcomed resource.
