In the years after initial publication, the authors could see that the book was well received worldwide for its friendly balance between the interplay between concepts and instructions for designs. More than 5 years have passed since the first expedition in 2008, and the development of technology has not been in vain. Much progress has been made in the field of wireless operating systems. It is that prompted the authors to add new information to the second book, so that the book is not only preserved in time, but also reflects the state of art.

This second article introduces the concept of degrees of freedom in vector transformation in Part 1. 2. To complete the 6 inverter control points. Especially the concept of flatness-controlled design of three AC machine systems is presented in an easy to understand and practical way. The concept of control and control was first introduced in the industry. 3. 6. 2. Then, the features of IM, DFIM and PMSM machine types were determined. Comparing more complex topics is not well understood by researchers in the field of intentional practice, as the authors see themselves as a bridge between theory and practice. Clear graphics were brought to the industry. 9. 2.2 IM, 9. 3.2 PMSM and 11. 3 for DFIM. At the end of the article, the main design of the so-called rest-relaxation process of plateau-based control is given in Appendix A.5.The authors published this second edition with the help of their esteemed teacher, Prof. Dr.-Eng. suitable. Dr. Rolf Schönfeld, founder of the Dresden School of Electrical Engineering at TU Dresden. If he were alive, he would celebrate his 80th birthday on June 27, 2014.The authors thank the German Academic Exchange Service (DAAD) and Prof. We thank Uwe Fusel from TU Dresden for his help in editing this second edition. The authors welcome any comments and suggestions for improvement that should be forwarded to N. P. Quang.

This book covers the design and development to control section of three-phase alternating current machines in squirrel cage rotor (IM) particle induction motors, permanent magnet synchronous motors (PMSM) and two-phase generators (DFIM). The German editions of this book, published by a specialist publishing house in 1993 and 1999, were well received by readers for their application-oriented and engineering-friendly approach. This experience inspired the authors to appeal to today’s audiences with this revised and expanded text in English. The new units take into account the latest developments in AC Drive technology on both the research and application side, providing the right amount of space to power two-phase machines and control the wireless motor.

The book focuses on vehicle control and mechanical systems and their controllable surfaces (speed and position) and provides the necessary scope for mechanical control functions. The latter form the basis of the operating system and can be divided into two groups:1. Basic algorithms such as space vector modulation, current control and rotor flux estimation. Operating system with the first set of functions can work satisfactorily. Integration of the second group can improve system signal quality parameters, change machine utilization and motor conversion, and support maintenance and commissioning.

After a summary of the basic characteristics of first- and three-phase alternating current motors and grid-controlled wind power plants, Sect. In Figure 1, inverter control for phase vector modulation is discussed in detail in Chapter 1. 2 Use a few examples to illustrate the application. Based on the basic machine equations, continuous and discrete machines of IM, PMSM and DFIM are derived from Chapter 2. 3. Unstructured lines of machines are shown here. Chapter 4 answers some questions about idea generation and implementation of executive control strategies. The design of a two-dimensional flow system using the discrete model will be discussed in more detail later in Chapter 2. 5 regarding other important issues such as control of limited variables. Various other operating systems were introduced.

Episodes. Figure 6 focuses on the group’s advanced control algorithm in response to problems such as the identification of machine parameters calculated from nameplate numbers and automatic precise parameter identification. Chapter 7 takes the complexity of adaptation one step further by discussing how to adapt rotors to the time constant IM, a critical problem to achieve in many engines. Energy efficiency issues weigh on The’s effectiveness, especially for high-powered vehicles. Chapter 8 focuses on these issues, particularly efficiency and optimal torque control strategies in the context of variable limit states.AC control software typically has linear algorithms, but the machine itself is characterized by a nonlinear operating model and a nonlinear operating state (limited by state variables) so that it can be described. An operating system that controls the wireless system from the beginning can be successful in most cases. One of these methods, the true linear classification method, is introduced in Chapter 1. 9 and more detailed information about the DFIM process is provided in Chapter 9. 11. Prior to this, Section.10 introduces the control system of wind power plants with DFIM, a practice that has become very useful in recent years.

During the preparation of this book the authors undertook to present the topics as accurately as possible, based on practical and practical requirements. The basic lesson is explained in as much detail as is necessary for our understanding; Numerous illustrations, graphs, diagrams and appendices support detailed description of the design process.

The book is the result of research and development carried out by the authors for more than 15 years. We hope to provide readers with not only a path, but also reliable and useful solutions to their systems and problems. Writers will appreciate this
