With the rise of high-risk process industrial equipment and aerospace vehicles, people pay more and more attention to the health of machines. From the perspective of biological evolution, machines are the continuation of organisms in another way. Both living people and running machines belong to dissipative structures. Struggle against machine faults and human diseases can follow some common laws. So, can machine failures “self-recovery” like humans and animals? The “Artificial self-recovery” proposed in this book is an Epiphany from the long-term struggle against equipment failures. “Introduction to Artificial Self-recovery” is the crystallization of the collective wisdom of my team in 32 years of plant practice and more than 20 years of scientific research.

In 1979, the author began to study and apply condition monitoring diagnosis tech-nology in Liaoyang Petrochemical Fiber Company (LYPFC)to solve the vibration faults of a compressor unit in trial run. Since 1991, the organization of mechan-ical research institute and instrument factory cooperation, in time and some compa-nies in the United States synchronous development of the application of local area network status monitoring system. Based on the author’s doctoral thesis “Fault Mech-anism and Diagnosis Method of High-speed Turbo Machinery Vibration” in Tsinghua University, in 1995, the author led the team to develop the “rotating machinery vibra-tion diagnosis software package” based on fault mechanism, which is the prototype of intelligent diagnosis expert system and has been popularized and applied in more than a dozen domestic enterprises with remarkable results. Up to now, I often think back to LYPFC colleagues who worked together day and night to overcome difficulties. I miss them forever!

The machine is a magnification of human functions thousands of times, it needs to continuously improve the system structure and control system to optimize its functions. This gave rise to Cybernetics and Engineering cybernetics, both of which study the purposeful behavior of machines, that is, the functions of machines. Human health is the first precious thing, and the health of machine systems created by humans is also important. With the rise of large industries and the development of aerospace vehicles, people are paying more and more attention to the health of machines.
