This book is a comprehensive treatment of data structures and algorithm analysis, that is, methods for organizing large amounts of data and estimating the running time of algorithms. As computers become faster, the need for programs that can handle large amounts of input data becomes more urgent. Ironically, this requires a greater focus on efficiency issues because programs become significantly less efficient when the input is large. By analyzing algorithms before actually programming them, students can determine whether a particular solution is feasible. For example, in this book students can look at specific problems and see how a careful implementation can reduce the time for a large amount of data from 16 years to less than 1 second. Therefore, the algorithms and data structures discussed in this book are analyzed with respect to their running time. In some cases, the subtle details that affect the running time of the implementation are also studied.

The book is divided into five chapters: servo motors, tachometer generators, synchros, resolvers and synchronous motors in automatic control systems. Starting from the basic electromagnetic relationships of various motors, the book explains their physical concepts and further analyzes their working principles and operating performance. Combined with the theoretical analysis of various control motors, the book introduces analysis methods such as the symmetrical component method, the transformation of the dq0 coordinate system and the air gap magnetic conductivity wave theory. The book gives examples of the application of various control motors in automatic control systems. At the same time, considering that the connection between the control motor and the system and its influence has become an important issue in use, a corresponding analysis of the dynamic characteristics of the control motor is made.
