The Brazilian executive named Erette Lucio, a senior engineer at the data processing center of the Brazilian Aerospace Industries, is very proficient in all kinds of aerospace-specific software, and because of this, when he saw the code, he was so calm, and let out the exclamation that he was living in a dream.

No way, if it were other code, Lucio might not be able to see the algorithm used, but there are two lines of mathematical collection characters in the code in front of him:

E=PB AND E=PB，THEN U=NB，

E=PB AND E=PM，THEN U=NB，

......

If anyone else saw this string of math set characters that were only slightly better than ghost drawings, their heads would probably explode, but Lucio was particularly familiar with this kind of math set characters, because he studied this kind of math set when he was studying for a Ph.D. in computer science at Columbia University in the United States.

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

This is a new type of mathematical algorithm and model theory born in the late 60s, the specific concept is very abstract, simply put, a bit like driving a car on the highway, in order to prevent car accidents, the old driver thinks and judges not "if the distance between the cars is how many meters, then how hard to brake." ”

Rather, it is an ambiguous judgment logic such as "if the distance between the workshops is small, slow down".

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

Based on this, even when faced with complex control objects, skilled operators can judge the situation by their own experience and skills and carry out better control, and the operator's so-called autonomous experience of "if the temperature starts to rise, then the fuel will be reduced a little" is used as a qualitative way to grasp the rules.

In this way, the skilled operator can express the qualitative rules in vague situations, such as if...... Rule...... Or if so...... Only......

Through these fuzzy thrusts, the desired amount of operation is obtained, which is the most basic underlying logic of fuzzy control theory.

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

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

It has also been implemented in the field of aviation, such as the automatic control of aircraft take-off and landing, and the control of helicopter propeller rudder and so on.

In a phrase that has been popular in the tech world decades later, fuzzy control theory belongs to the core infrastructure of artificial intelligence.

Of course, this is a matter of decades later, in the mid-nineties, this advanced algorithm built on the computer side is the black technology of the black technology, because after the application of this set of algorithms, under the control of the computer, all kinds of products have preliminary artificial intelligence performance.

This kind of product may not be a big deal in a few decades, but in the mid-90s, it was a proper black technology, and industrial products actually had brains and could think about what to do...... Rule...... This kind of complex logic that can only be figured out by humans, this is not black technology, what is still black technology.

If this were not the case, Lucio, who had just received his Ph.D. from Columbia University in the United States a few years ago, would not have taken fuzzy control theory as his main direction when he was studying for his Ph.D.

Of course, with Lucio's ability and insight, even if he sees an algorithm or software based on fuzzy control theory, he will not be so out of shape, after all, this kind of concept was proposed in the 60s, has been applied to the field of industrial control in the 70s, and the mathematical theory that began to be widely popularized in the 80s has been applied enough in the mid-90s.

As the main direction of his doctoral dissertation, Lucio is not an authoritative expert in the field, but he can also be called a veteran.

It is impossible to be like now, eager to incarnate Sadako in "Midnight Bell", and reverse drill into the rear projection screen to find out.

There is no way that the application of this code in front of me is too cutting-edge, and 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 Indian natives who have just come out of the primeval forest, and when they realize that they can control the world by drilling wood for fire, they find that people outside can play with the fire with a lighter at will.

That's why Lucio was so shocked that he couldn't speak incoherently.

Because Lao Zhong introduced that this new algorithm is not applied to subway lines, let alone oil drilling, but to the full digital electronic control system of aero engines.

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

The United States is the leader in this regard, but even so, in the theory of fuzzy control of aero engines, the Americans are only theoretically at this stage, and the practical application has not been carried out.

As a result, China's Ascendas Group has applied what even the United States, which has extremely advanced aviation technology, has applied to the architecture of its own aero-engine full-authority digital electronic control system.

What does it mean to directly cross the theorists of the United States and advance to the action school?

Quite simply, China Tengfei Group is not only extremely profound in fuzzy control theory, but also far behind the vast majority of countries, including the United States, in practical application.

This made Lucio, who studied in the United States since he was an undergraduate, studied until he graduated with a doctorate, almost regarded the United States as a beacon of human science and technology, and worshiped that except for alien civilizations that can destroy the United States, no country on the earth can catch up with the United States in technology.

Under such circumstances, how can this doctor from Columbia University not be shocked, and how can he not be shocked!

"You ...... You guys...... Have you read that academic report?" I don't know how long it took for Lucio to slowly calm down from his shock, and immediately looked at Lin Guanghua and Lao Zhong, and asked an inexplicable word.

Lin Guanghua didn't know what Lucio would say, so he could only look at Lao Zhong, but Lao Zhong's unpretentious face smiled heartily: "You mean the "Application of Fuzzy Controller in Aero Engine Fuel System" delivered at the 14th International Aero Engine Academic Annual Conference held in Ohio, USA the year before last, right?"

Lucio nodded, "Yes!"

"Of course we have seen it, otherwise how could there be the current application? After all, we have always crossed the river by touching 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 theory of developed countries is a good fertilizer and soil for their training results, and they can harvest fruitful fruits anytime and anywhere, but Lucio almost didn't come up in one breath to hold back his internal injuries, and said in his heart that he could still play like this?
