Electrical machines are being widely used today in traction systems, robotics, and other position control systems. The modern applications demand advanced control techniques with high precision. The Direct Torque Control (DTC) method is one of the highest performance control strategies for AC machines to provide rapid torque and flux control. It is widely known to produce a quick and fast response in AC drives by selecting the proper voltage space vector according to the switching status of the inverter. The main advantage of DTC is its simple structure. Within this framework, this book entitled Direct Torque Control Strategies of Electrical Machines consists of a representation of theoretical results related to design and advanced control of AC machines and the diagnostics of electrical machine drives and generators involved in automotive systems. The priority has been focused on the DTC approach applications with and without commutation frequency control. It also covers DTC applications using artificial intelligence.

This book consists of seven chapters that have been written by leading researchers covering recent theoretical developments and applications of DTC strategies. It combines theoretical analysis, simulation, and experimental concepts. It is expected that readers require background knowledge to understand various concepts and results presented in this book.

Finally, the editor would like to express their sincere gratitude to authors from all over the world for submitting their high-quality work in a timely manner and revising it appropriately at short notice. A particular thanks and my deepest gratitude to the IntechOpen editorial staff for their continuous support, assistance, and significant improvement in the manuscript. Without their help, the book would not be published as scheduled.
