Chapter 920

The speech is that the Brazilian executive named erete Lucio is a senior engineer in the data processing center of Brazil Aerospace Industry Corporation. He is very proficient in all kinds of aerospace special software. Because of this, when he saw that code, he would be so calm and exclaim that he was living in a dream.

No way, Lucio may not be able to see the algorithm in other codes, but there are two lines of such mathematical set characters in this Code:

e = pbande = Pb, thenu = Nb,

e = pbande = PM, thenu = Nb,

If other people see this series of mathematical set characters which are only slightly better than ghost characters, they will be shocked. However, Lucio is especially familiar with this kind of mathematical set characters, because he studied this kind of mathematical set when he was a doctor of computer science at Columbia University.

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

This is a new mathematical algorithm and model theory, which was born in the late 1960s. The specific concept is very abstract. To put it simply, it's a bit like driving a car on a highway. In order to prevent traffic accidents, the old driver's thinking and judgment is not "if the distance between cars is how many meters, how much strength to brake."

It's a kind of ambiguous judgment logic like "if the workshop distance is small, slow down".

This kind of "small" and "slow down" ambiguous language in the form of fuzzy sets, the experience between people, skills in the form of control rules to the computer is the so-called "fuzzy control".

Based on this, even in the face of complex control objects, skilled operators can judge the situation by their own experience and skills, and make better control. The operator's so-called "if the temperature starts to rise, the fuel will be reduced a little" independent experience is used as qualitative to master the rules.

In this way, skilled operators can express qualitative rules in fuzzy situations, such as if Then Or if Just

Through these fuzzy thrusts, we can get the desired operation quantity, which is the basic logic of fuzzy control theory.

With this logic, the control software can be constructed by practical algorithm, and then combined with computer, 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 the hydraulic tunneling machine in the field of oil exploitation; the control system of industrial robots such as welding robots, grinding robots, laser cutting robots, etc.

There are also many applications in the aviation field, such as the automatic control of aircraft take-off and landing, and the control of helicopter propeller and rudder.

In a popular phrase in the science and technology circle decades later, fuzzy control theory belongs to the core infrastructure of AI Artificial Intelligence.

Of course, it will be decades later. In the mid-1990s, this kind of advanced algorithm based on computer is black technology in black technology, because after applying this set of algorithm, under the control of computer, all kinds of products will have preliminary artificial intelligence performance.

This kind of product may be nothing after decades, but in the mid-1990s, it was a proper black technology. Industrial products actually had brains and could think about if Then This kind of complex logic can only be understood by human beings. It's not black technology, but black technology.

If not, Lucio, who just got his doctorate from Columbia University in the United States a few years ago, doesn't need to take fuzzy control theory as his main research direction.

Of course, with Lucio's ability and insight, even the algorithm or software based on fuzzy control theory will not be so out of fashion. After all, this concept was put forward in the 1960s, has been applied to the field of industrial control since the 1970s, and the mathematical theory which began to be widely popularized in the 1980s has been applied enough in the mid-1990s.

As the main direction of his doctoral dissertation, Lucio is not an authoritative expert in this field, but also a senior person. Generally speaking, seeing the application of fuzzy control theory, Lucio basically passed away with a smile, most of which is just a few words of praise like commercial boasting.

It's impossible to be like this now. I wish I could incarnate Zhenzi in "midnight bell" and go back into the rear projection screen to find out.

I can't help but think that the application of this code is too cutting-edge. Lucio, a senior person who specializes in fuzzy control theory, has just contacted the relevant literature and actually saw the practical application.

It's like the Indian aborigines who have just come out of the virgin forest, when they consciously master how to make a fire by drilling wood, they find that people outside can play with the fire with a lighter. It's not as simple as MMP in their heart, but they feel that they have encountered miracles.

That's why Lucio's words are incoherent.

Because Mr. Zhong introduced this new algorithm, which is not applied to subway lines, not to mention oil drilling, but to the full digital electronic control system of aeroengine.

In the current fuzzy control theory, subway, oil, industrial robots and even household appliances are not cutting-edge, it is precisely the control of aeroengine that is the top of the tower.The United States is the leader in this field, but even so, in the theory of aero-engine fuzzy control, the United States is still in theory at this stage, and the practical application has not started.

As a result, China's Tengfei group has applied it to the architecture of its own full digital electronic control system for aero engines, even though the United States, which is extremely advanced in aviation technology, has not achieved anything.

What does it mean to go directly beyond the theorists in the United States to the activists?

Quite simply, China Tengfei group is not only very sophisticated in fuzzy control theory, but also far behind most countries including the United States in practical application.

This made Lucio, who studied in the United States from his undergraduate education to his doctoral degree, almost regarded the United States as a beacon of human science and technology. He worshipped Lucio, who believed that no country on earth could catch up with the United States in technology except the alien civilization. He firmly believed in the three outlooks for decades and almost did not collapse directly.

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

"You You Have you read that academic report? " I don't know how long it took Lucio to recover from his shock. He immediately looked at Lin Guanghua and Lao Zhong and asked a strange question.

Lin Guanghua didn't know what Lucio said, so he could only look at Lao Zhong, whose simple face gave him a hearty smile: "you mean the application of fuzzy controller in Aeroengine Fuel System published at the 14th International aeroengine annual conference held in Ohio, USA the year before last?"

Lucio nodded: "yes!"

"Of course we have. Otherwise, how can we have the current application? After all, we have been following the technological theories of developed countries, so as long as we feel that they are reasonable and feasible, we will roll up our sleeves and put them into application! "

What Mr. Zhong said was that he was very proud, as if the technology theory of developed countries was the good fertilizer and soil for their training results, and he could harvest rich fruits anytime and anywhere. However, Lucio almost didn't come up at a breath and suffered from internal injury. He said that he could play like this?
