Take Off My Aviation Era

It was the Brazilian executive named Errett Lucio, a senior engineer in the data processing center of Embraer Aerospace Industries, who was very proficient in all kinds of special aerospace software, and because of this, when he saw the code Only then will I be so uncomfortable, exclaiming that I am living in a dream.

No way, if it is other code, Lucio may not really be able to see the algorithm used, but there are two lines of 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 that are only slightly better than ghost symbols, they will probably blow their heads. However, Lucio is particularly familiar with such mathematical set characters, because he is studying computer science at Columbia University in the United States. When I was Ph.D., I studied this kind of mathematical set.

In the field of mathematics and computer applications, this set of mathematics 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. Simply put, it is a bit like driving a car on a highway. In order to prevent a car accident, the old driver’s thinking and judgment is not "if the car If the distance is how many meters, the brakes should be braked harder."

It is the ambiguous judgment logic of "if the distance between 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 between people are transmitted to the computer in the form of control rules. This is the so-called "fuzzy control". ".

Based on this, even if a skilled operator is faced with a complex control object, he can judge the situation based on his own experience and skills, and perform better control. The operator’s so-called “if the temperature starts to rise, the fuel will decrease a little bit” autonomous experience Master the rules as qualitative.

In this way, skilled operators can express qualitative rules in a vague situation, such as if... then... or if... just...

Obtaining the desired amount of operation through these fuzzy thrusts is the most basic logic of the fuzzy control theory.

With this kind of logic, control software can be constructed through practical algorithms, 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 operation system of the hydraulic tunneling machinery in the oil exploration field; the operation system of industrial robots such as welding robots, grinding robots, and laser cutting robots.

There are also many implementations in the aviation field, such as the automatic control of aircraft take-off and landing; and the control of helicopter propellers and so on.

To use a popular phrase in the science and technology circle decades later, that is, fuzzy control theory belongs to the core infrastructure of AI artificial intelligence.

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

This type of product may not be a big deal decades later, but in the mid-1990s, it was a proper black technology. Industrial products actually have brains and can think about if... then... this kind of human beings can figure out the complexity. It's logical, this is not black technology, what is black technology.

If not, Lucio, who just received his Ph.D. from Columbia University in the United States a few years ago, doesn’t need to use fuzzy control theory as his Ph.D.

Of course, with Lucio’s ability and insight, even if he sees algorithms or software based on fuzzy control theory, he won’t be so frustrated. After all, this concept was put forward in the 1960s and has been applied to the field of industrial control in the 1970s. The mathematics theory that began to be widely used in the mid-1990s 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 he can also be called a senior person. In general, seeing the application of fuzzy control theory, Lucio basically smiled. It's over, at most a few compliments like commercial bluffs.

It is absolutely impossible to be like this, wishing to incarnate Sadako in "Midnight Ring", back into the rear projection screen to find out.

There is no way that the application of the code in front of you is too cutting-edge. The 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 feels like the native Indians who have just walked out of the virgin forest, consciously mastering that they can control the world by drilling wood to make fire, only to find that people outside can play with fire at will with a lighter. It is no longer as simple as MMP in their hearts. I feel that I have encountered a miracle.

Therefore, Lucio was shocked to speak incoherently.

Because Lao Zhong introduced that this new algorithm is not applied in subway lines, not in oil drilling, but in aero-engine full-power digital electronic control system.

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 aero-engines that is the top spire.

The United States does its part to be the leader in this area, but even so, in the theory of fuzzy control of aero-engines, the Americans are at this stage only staying in theory, and practical applications have not started.

As a result, even the United States, where aviation technology is extremely advanced, has not achieved something, but China’s Ascendas Group has applied it to the architecture of its own aero-engine digital electronic control system ~www.readwn.com~ directly oversteps the American theory. School, advanced to action school, what does this mean?

Quite simply, China Ascendas Group is not only extremely sophisticated in fuzzy control theory, but also far behind most countries, including the United States, in practical applications.

This allowed him to study in the United States from the beginning of his undergraduate studies until he graduated with a Ph.D., and he almost regarded the United States as a beacon of human science and technology, and worshipped that no country on earth could surpass the United States in technology, except that alien civilization could destroy the United States Lucio's three views that had been firm for decades almost didn't collapse directly.

Under such circumstances, how can the Columbia University Ph.D. not be shocked, how can he not be surprised!

"You...you...have you read that academic report?" I don't know how long it took before Lucio calmed down from the shock. He immediately looked at Lin Guanghua and Lao Zhong, and asked something inexplicable. .

Lin Guanghua didn’t know what Lucio said, so he could only look at the old clock. However, old clock’s unpretentious face smiled heartily: "You mean the 14th International Aero Engines held in Ohio, USA the year before. "The Application of Fuzzy Controller in Aviation Engine Fuel System" published at the annual academic conference, right?"

Lucio nodded: "Yes!"

"Of course we have seen it, otherwise, how can there be current applications? After all, we have been crossing the river with the technological theories of developed countries, so as long as we feel reasonable and feasible, we will roll up our sleeves and put them into application!"

What Lao Zhong said is very proud, as if the technical theory of developed countries is a good fertilizer and soil for their training results, and they can harvest fruit anytime and anywhere, but Lucio almost didn't come up with internal injuries in one breath. , Xin said he could still play like this?
