"Engineering Cybernetics", first published in 1954, is the language of the first edition in English. It explores the extension of cybernetics to the field of engineering technology.
Qian Xuesen was born in Shanghai in 1911 and died in 2009. He is an aerodynamicist, a systems scientist, one of the founders of engineering cybernetics, a member of the Chinese Academy of Sciences, an academician of the Chinese Academy of Engineering, and the winner of two bombs and one satellite.
Qian Xuesen graduated from the Department of Mechanical Engineering of Jiaotong University in 1934 ; in 1935 , he went to the United States to study at the public expense of the Seventh Boxer Indemnity; in 1936 , he graduated from the Massachusetts Institute of Technology with a master's degree, and then transferred to the Department of Aeronautics of the California Institute of Technology, where he studied under the tutelage of Western Otto von Karman; obtained a doctorate in aviation and mathematics from the California Institute of Technology in 1939 , and then stayed to teach; in 1945 , he was sent to Germany to investigate Nazi Germany's rocket technology; in 1955 , with the efforts of Chairman Mao and Premier Zhou Many American pilots captured in the Korean War air battle were exchanged back to China; in 1956 , he became the first director of the Institute of Mechanics of the Chinese Academy of Sciences; in 1957 , he became the first director of the Fifth Research Institute of the Ministry of National Defense, and was elected as the Chinese Academy of Sciences in the same year. Member of the Faculty (Academician); Founded the Department of Modern Mechanics of the University of Science and Technology of China in 1958 and served as the first director, joined the Communist Party of China in 1959; was co- elected as the Executive Chairman of the Presidium of the Chinese Academy of Sciences in 1984; Chairman of the Committee; Vice-Chairman of the Sixth, Seventh and Eighth National Committee of the Chinese People's Political Consultative Conference from 1986 to 1998; Awarded the Merit Medal of Two Bombs and One Star in 1999; October 2009Died in Beijing on the 31st at the age of 98.

In the age of Qian Lao, he realized the important impact of computers on human society. However, for the vast majority of ordinary Chinese, the relatively convenient and cheap access to computers has actually reached the end of the 20th century and the beginning of the 21st century. The scientific community must be at the forefront of the boundaries of human knowledge, and the industrial community is responsible for transforming the scientific community's concepts, ideas, and prototypes into products that are affordable to most consumers.
One of the cores of engineering cybernetics is to think about how to ensure the combination of relatively simple links in the process of designing complex systems, and how to combine them is the key. This process involves mutual cooperation between the various components. To understand a complex system, you must look at it from the perspective of the system, understand the system first, and then think about the details.
Qian Lao estimated that in the year 2000, the world's nuclear power generation accounted for 45% of the world's total power generation. As we look at today, this estimate clearly overestimates the penetration rate of nuclear energy. Although nuclear energy is a clean energy source, it carries great risks. Once a nuclear leakage accident occurs, its harm is far-reaching. The Chernobyl incident in the Soviet Union and the Fukushima incident in Japan have all led to concerns about the safety of nuclear power plants.
Qian Lao's estimates for nuclear power plants are overly optimistic, while his expectations for computers are relatively conservative. Predicting the future is such fun. Events we thought were highly probable may not have happened, but the aspects of our lack of awareness may bring unimaginable rewards.
We summarize experience from production practice, but if we only stay in a specific behavior itself, without extracting common characteristics from the behavior, we cannot form a theory. The theory comes from reality, but must be higher than reality. We need to be able to see the essence through the phenomena.
For different systems, we may have different metrics. For example, for some systems, we want to reduce energy consumption as much as possible; for some systems, we want to reduce the mean square error. But stability is an inevitable expectation of almost all systems, that is, predictability of results is what we are after.
The variable coefficient system is complex. In order to study complex problems, we hope to use the constant-coefficient system to simulate in some cases. Use the conclusions drawn in relatively simple cases to help us understand more complex systems. If we start with a complex system to analyze, the complexity may lead us to lose our clues.
Anti-interference is also an important indicator for evaluating a system. It is like a person who can make stable decisions and maintain stable efficiency without being affected by noise or negative external influences at all. However, when there is a disturbance, the chain may be dropped and the market can be exploited. Only with strong anti-interference ability can adaptability be strong.

A great work written by the father of the Chinese space program while at Caltech. He was later sent back to China due to unfounded charges of having communist sympathies. It assumes a basic understanding of differential equations and methodically presents many topics and techniques of controls engineering.
