The motion of the train depends on the traction of linear motors in the vehicle. This book describes a number of essential technologies that can ensure the safe operation of Maglev trains, such as suspension and orientation technologies, network control and diagnosis technologies.

This book is intended for researchers, scientists, engineers and graduate students involved in the rail transit industry, train control and diagnosis, and Maglev technology.

This book highlights the system modeling, control, diagnosis and fault-tolerant design of the suspension, and guidance system of the high-speed maglev train based on electromagnetic suspension technology. The electromagnetic suspension technology has been widely used in real-life engineering, including maglev trains, magnetic bearings, magnetic levitation vibration isolators, magnetic suspension and balance systems for wind tunnels, etc. 

Based on the academic researches, engineering applications, and technical innovations of high-speed maglev trains carried out by the maglev team of the National University of Defense Technology, this book summarizes the technical achievements in the field of levitation and guidance control technology of high-speed maglev train.

It analyzes the research status and challenges of the suspension control technology of the electromagnetic suspension maglev train. The suspension, guidance system modeling, and controller design of the high-speed maglev train are described in detail. The performance index and performance evaluation method of the levitation and guidance system under various working conditions are analyzed respectively. A suspension scheme of permanent magnet electromagnetic hybrid suspension high-speed maglev train is proposed, and the results of the vehicle test are given in order to further improve the suspension energy consumption and heating of electromagnetic suspension high-speed maglev train. The suspension and guidance fault diagnosis and tolerant control methods of the high-speed maglev train are studied to improve the system''s safety and reliability. The research and application results of suspension control technology of electromagnetic suspension maglev train are fully displayed for readers.

This book is intended for researchers, scientists, engineers, and graduate students involved in the rail transit industry, train control and diagnosis, and maglev technology.

This book introduces techniques and methods of the lymphadenectomy and the angioplasty under thoracoscope. It also presents the latest 2 cm uniportal lobectomy, which represents the highest level of thoracoscopic lung surgery technique. Compared to traditional thoracoscopic surgery, the survival and quality of postoperative life of patients undergoing lung cancer surgery have been greatly improved. This book provides a brand-new vision for thoracic surgeons to understand and learn the latest and most advanced development status and direction of modern minimally invasive techniques in thoracic surgery. The video screenshots fully reflect the real process of the operation and unique surgical methods. Thoracic surgeons will benefit from this book and improve the level of minimally invasive techniques in thoracic surgery.
