Chapter 920: Crossing the River by Feeling the Technical Theory of Developed Countries

    The speaker was a Brazilian executive named Eret Lucio. He was a senior engineer at the Data Processing Center of the Brazilian Aerospace Industry Corporation. He was very proficient in various aerospace-specific software. Because of this, when he saw that piece of code  Only then did he become so restless and exclaimed that he was living in a dream.

    There is no way. If it were other codes, Lucio might not be able to see the algorithm used, but there are two lines of mathematical set characters like this in the code in front of him:

    ??e=pbande=pb£¬thenu=nb£¬

    e=pbande=pm£¬thenu=nb£¬

    ¡­¡­

    If other people see this string of mathematical set characters that are only slightly better than ghost symbols, their heads will probably explode. However, Lucio is particularly familiar with this type of mathematical set characters because he studied computer science at Columbia University in the United States.  It was this kind of mathematical set that I studied during my Ph.D.

    In the fields of mathematics and computer applications, this mathematical set is also called fuzzy control theory.

    This is a new mathematical algorithm and model theory born in the late 1960s. The specific concept is very abstract. To put it simply, it is a bit like driving a car on the highway. In order to prevent car accidents, experienced drivers think and judge not "if the car  If the distance is several meters, how hard should the brakes be?"

    Rather, it is an ambiguous judgment logic such as "If the distance between vehicles is small, then slow down."

    This kind of expression of ambiguous language such as "small" and "deceleration" in the form of fuzzy sets, and transferring the experience and skills between people to the computer in the form of control rules is the so-called "fuzzy control"  ".

    Based on this, even if a skilled operator faces complex control objects, he can judge the situation based on his own experience and skills and perform better control. The operator's so-called autonomous experience of "if the temperature starts to rise, reduce the fuel a little"  Master the rules as qualitative.

    In this way, skilled operators can express qualitative rules in vague situations, such as ifthenor ifthen

    The desired operation quantity is obtained through these fuzzy thrusts. This is the most basic underlying logic of fuzzy control theory.

    With such logic, through practical algorithms to form control software, and combined with computers, it can be widely used in many fields.

    For example, the automatic operation system of the subway; the control system of the tunnel shield machine; the control system of hydraulic excavation machinery in the field of oil extraction; the control system of industrial robots such as welding robots, grinding robots, and laser cutting robots.

    There are many implementations in the aviation field, such as automatic control of aircraft takeoff and landing; another example is helicopter propeller control, etc.

    To use a popular saying in the technology circle decades later, fuzzy control theory belongs to the core infrastructure of AI artificial intelligence.

    Of course, this was decades later. In the mid-1990s, this advanced algorithm built on computers was a black technology among black technologies, because after applying this set of algorithms, under the control of the computer, all kinds of  The product will have preliminary artificial intelligence capabilities.

    This kind of product may not matter a few decades later, but in the mid-1990s, it was a complete black technology. Industrial products actually have brains and can think about what ifthensuch complex things that only humans can understand.  Logic, this is not a black technology, it is still a black technology.

    If this were not the case, Lucio, who had just received his PhD from Columbia University in the United States a few years ago, would not have considered fuzzy control theory as his main focus during his PhD studies.

    Of course, with Lucio's ability and knowledge, he would not be so out of control even if he saw algorithms or software based on fuzzy control theory. After all, this concept was proposed in the 1960s and has been applied to the field of industrial control in the 1970s.  The mathematical theory that became widely popularized in the 1990s had enough applications by the mid-1990s.

    As Lucio, who took this as the main focus of his doctoral thesis, is not an authoritative expert in this field, but he can also be called a senior person. Under normal circumstances, Lucio basically smiles when seeing the application of fuzzy control theory.  It just passed. At most, it was just a few words of compliments like business bragging.

    It will never be like this. I wish I could transform into Sadako in "The Ring" and get into the rear projection screen to find out.

    There is no way. The application of the code in front of me is too cutting-edge. Lucio, a veteran who specializes in fuzzy control theory, has just come into contact with relevant literature and has actually seen practical applications.

    It feels like the native Indians who have just stepped out of the virgin forest, and when they feel that they can control the world by drilling wood to make fire, they find that people outside can just take a lighter and play with the fire at will. This is no longer the case.It was so simple, but I felt like I had encountered a miracle.

    That¡¯s why Lucio was so shocked that he was speechless.

    Because the new algorithm introduced by Lao Zhong is not used in subway lines, let alone oil drilling, but in aerospace engine full-power digital electronic control systems.

    In terms of current fuzzy control theory, subways, petroleum, industrial robots and even home appliances are not at the forefront. It is precisely the control of aerospace engines that is the top spire.

    The United States is undoubtedly the leader in this area, but even so, in the theory of aero-engine fuzzy control, the Americans are still just in theory at this stage, and practical applications have not been carried out.

    As a result, China's Ascendas Group has applied something that even the United States, which is extremely advanced in aviation technology, has not implemented in the architecture of its own aerospace engine's full-power digital electronic control system.

    What does it mean to directly surpass the theoretical school in the United States and advance to the action school?

    It¡¯s very simple. China Ascendas Group is not only extremely sophisticated in fuzzy control theory, but also far behind most countries, including the United States, in terms of practical application.

    This made me study in the United States from the beginning of my undergraduate degree until I graduated with a doctorate. I almost regarded the United States as a beacon of human science and technology. I admired the United States and believed that except for alien civilizations that could destroy the United States, no country on earth could catch up with the United States in technology.  Lucio's three-dimensional outlook that he had held firm for decades almost collapsed.

    How could this doctor from Columbia University not be shocked under such circumstances? How could he not be shocked!

    "Youyouhave you read that academic report?" I don't know how long it took for Lucio to slowly calm down from the shock. He immediately looked at Lin Guanghua and Lao Zhong and asked an inexplicable question.  .

    Lin Guanghua didn't know what Lucio was going to say, so he could only look at Lao Zhong, but Lao Zhong's simple face smiled heartily: "Are you talking about the 14th International Aero Engine held in Ohio, USA the year before last?  "Application of Fuzzy Controller in Aeroengine Fuel System" published at the annual academic conference, right?"

    Lucio nodded: "Yes!"

    "Of course we have seen it, otherwise how could we have the current application? After all, we have always followed the technical theories of developed countries, so as long as we think it is reasonable and feasible, we will roll up our sleeves and put them into application!"

    Lao Zhong said this with great pride, as if the technical theories of developed countries are good fertilizer and soil for their training results, and they can harvest rich fruits anytime and anywhere. However, Lucio almost couldn't hold in his breath and suffered internal injuries.  , I thought that I could still play like this?
