This book discusses the major equipment and systems working reliably in extreme environments such as vibration, impact, centrifuge and large temperature range, which requires a full understanding and grasping of the basic theories and key technologies of electrohydraulic servo control in extreme environments. The author combines years of practical experience in the development of major equipment and systems, including the National Key Research and Development Plan of China, National Natural Science Foundation of China, Aviation Fund, basic research and model tasks of research institutes, and systematically summarizes the basic achievements and practical cases of more than 30 years of dedicated research on electrohydraulic servo control theory, involving aviation, aerospace, shipbuilding, intelligent machinery, and marine equipment. This book is a good reference to scientific and technological personnel engaged in the research, design, manufacturing, testing, and management of high-end fluid transmission and control systems and devices for major equipment, major engineering, and key fields.
