I failed a course, and the system became my study supervisor.

Chapter 81 Bottleneck and Breakthrough
Relying on previous experience, the research team is like standing on the shoulders of giants, able to see farther and walk more steadily.

In just one month, independent simulation modules for lithium batteries, supercapacitors and PEMFC were fully established.

Moreover, when the simulation experiment is conducted independently, the deviation from the actual experiment is very small and can be completely ignored.

This is a breakthrough!
"We have completed the first phase of the ABS project, which is a cause for celebration!

......"

Zhou Chengkang was very happy and gave a long and passionate speech of encouragement in front of all the experimenters.

The enthusiasm of most team members was aroused.

In reality, however, while research enthusiasm can be inspiring, its impact is limited.

Faced with the sudden bottleneck, the fiery enthusiasm was instantly poured with a basin of cold water. It cannot even be described as extinguished, it was as if a layer of frost had formed.

According to the research plan, the task of the second phase is to combine the three independent simulation modules into a complete ABS simulator.

To achieve this goal, Xu Ling and many professors discussed and concluded that they would draw on the experience of adding the PEMFC thermal system module and continue to use the HIL method to connect the three blocks.

But imagination is rich, but reality is very skinny.

When only the Li-ion battery module and the supercapacitor module were connected via the HIL, everything worked perfectly and the simulator performance did not degrade much.

But once the PEMFC was added, everything went haywire. Although the connections were programmatically complete, the simulator simply gave up when it came time for real-world testing.

When I want to run a simple data, it takes a long time to run.

Of course, people have subjective initiative. Once a problem is discovered, the research team will immediately mobilize.

Many redundant or inefficient codes in individual modules have been deleted or improved.

But the result was still unsatisfactory, the simulator still couldn't run. Like a lame horse, it made people sigh with regret.

"Student Xu Ling, what do you think?"

Zhou Chengkang said solemnly.

"I think it might be a problem with the HIL. We have done a good job with our own individual modules."

Xu Ling thought for a moment and put forward his own idea.

"But as it stands now, HIL is the most reliable and efficient method available."

A professor from the School of Computer Science said.

"Professor Wang, efficiency is only relative. We don't know the structure of its internal code and algorithm.

To put it in a more vivid way, HIL might be a spoon, which is indeed very convenient when eating porridge. But is it possible that our ABS is noodles?

What I want to say is that HIL may not be suitable for our nested and multi-module simulation model."

Xu Ling explained patiently.

But this does not mean that the professor's academic level is insufficient. It is simply because the HIL method is not only new, but also its application field is completely different from the professors' research direction.

"So, you think we should abandon HIL and try a different approach, right?"

Zhou Chengkang understood what Xu Ling meant.

"Correct!"

Xu Ling answered firmly.

If this road is clearly blocked, why do we continue to follow it?

Only by being flexible and adaptable can we solve problems.

But giving up HIL means losing the existing experience.

The research team needs to start completely from scratch and redesign an algorithm as a bridge to connect the three independent parts.

The work was extremely difficult to advance. The teachers and students of the School of Computer Science worked overtime every day to study, but there was no progress.

As the project manager, Zhou Chengkang saw it all and was worried.

Those who write algorithms are busy and exhausted, while those who are waiting to do experiments are bored.

How is this a problem!
"I'll go to the School of Mathematics and borrow some people!" This was the solution Zhou Chengkang came up with.

Xu Ling naturally also participated in the design of the algorithm, but also did not make any breakthroughs.

This triggered Xu Ling's thinking.

Why does it work fine when running independently, but not when connected together? Are all modules optimized?
……

and many more!

Independence?

How can the three parts be independent?

Xu Ling suddenly woke up.

Lithium batteries, supercapacitors and PEMFCs operate under different working conditions, but this does not mean that they are completely independent.

To cope with sudden changes in power, it is necessary to switch from PEMFC to lithium batteries, and supercapacitors are also needed in the middle.

In this extremely short moment, the working conditions of the three should be the same, and the characteristic equations of the three should be satisfied at the same time!
Previous algorithm designs have always adopted independent parameter design, performed serially or in parallel, and no critical equation was established when the working state was switched.

So this is where the problem lies!

Xu Ling was pleasantly surprised, yet also a bit annoyed. It was clearly his system, and it was fine if others hadn't noticed it, but he himself hadn't noticed such an obvious problem.

It really proves the saying that those who are in the know are often the most confused.

Now that the problem has been found, Xu Ling can naturally prescribe the right medicine.

During the discussion with everyone, a solution came into being, and Xu Ling gave it a misleading name - pseudo-independent test.

That is, based on the corresponding mathematical relationship, the working states of the three modules are temporarily made equivalent at this moment.

With the pseudo-independence test, the algorithm design progress has been significantly accelerated.

But this acceleration is like going from 0 to 1, while the overall progress is 100.

Therefore, from the overall perspective, the design of the algorithm is still difficult to make any progress.

Now, Xu Ling was really at a loss.

His Linguistics level 1 and Informatics level 0 seemed unable to support him to go further.

How to do?
We can't just stay stuck here like this!

Just when he was at a loss, Xu Ling thought of the system that had not popped up for a long time.

To be more precise, it is a drawing table!

"Please provide an optimized solution for the three-module connection based on all the existing data, methods, and ideas!"

Xu Ling said these words in his heart with full of hope.

Fortunately, the system did not directly state that the level was too low.

This means there is hope!
[Drawing in progress, please wait...]

Immediately afterwards, a line of text appeared, which made Xu Ling feel slightly relieved.

But Xu Ling didn't dare to relax completely, as he still remembered the sky-high price of drone wings for 1000 motivational points last time.

"Ding!"

"ABS Bridge successfully drawn! Requires 300 motivation points + 300 study points!"

Conscience system!

Xu Ling suddenly became extremely excited and tremblingly clicked on the drawing icon on the floating screen.

In just a few seconds, a manual with several pages of A4 paper appeared in Xu Ling's hand, with ABS Bridge written on the title page.

ABS bridge!
This name is so appropriate and completely in line with Xu Ling's design concept.

And the content inside did not disappoint Xu Ling.
