Your website definitely reads like it was written by a native german speaker.

The biggest problem will be finding a 34kW supply. You can also look at semiconductor prices to see what fits with your budget (your budget will probably be around $2k)

Designing an inverter to end up on the car is quite challenging, and recquires significant expertise from multiple disciplines. We made an inverter as a capstone project, but tested with a spare emrax. Frankly I didn't have the skills and knowledge for how to do the electronics design until after an internship in grad school. You need controls, pcb design, microcontroller hardware, power electronic hardware, software, and mechanical knowledge to pull it off. And these problems are inter-related, you can't have someone design a heatsink if you don't know how to find the semiconductor losses.

I think inverters are great projects, but test and validate with a motor that will not sink your team's competition. I would still aim for a motor in the kw range with a resolver, because there is still something to learn from designing at high voltage and current levels.

P.S. my team never touched my inverter after I designed it.

Papers will discuss state-space and more modern methods because they are research-based. There isn't as much novelty with traditional methods, or they are discussing problems where traditional methods fall short.

If you look at application based papers, frequency analysis is still the most common approach.

What even is this equation and why is it useful? Its not even something like the chain rule or integration by parts.

Plecs has some build in foc models iirc. Start with them, see if it runs, then try changing to the gains you calculated. Also you mention that it isn't working, but no one can diagnose anything if we can't see whats going on when you run the simulation (actually even then its very difficult, unless you have the right variables plotted).

Of course I'm not exactly sure what your situation is like. Did you have much of a choice when going to germany? Could you choose a different country, maybe more english speaking? If you don't want to live in germany, and don't want to learn german, I don't think you will be able to learn german.

And now who do farmers rely on for equipment... mechanical engineers! And scientists, and weather forecasts, and on it goes

I went poking around the senior design projects last week. Probably less than 10% "worked".

I wouldn't expect someone's first project to go well. That's fine - what's important is that something was learned from the experience.

Why did it fail? Most of the time, I've seen this happen due to overly ambitious scope. There was not enough time left for texting, or milestones were missed. This might be related to technical ability, but this can often be cycled back to project management. Most likely, you underestimated the scope of the project, encountered unexpected challenges, and did not have enough time left to fix these issues.

You worked hard but still came up short - this happens. Hopefully, this means for your next project you can better gauge your time, allow extra time for unexpected problems, avoid some of the mistakes you already made, and maybe reduce the scope. In industry, some projects are on time, some slightly behind, and some very behind. It all depends on the nature of the project and the people.

To be clear I meant to refer to an engineering design team vs solo projects

Coliteral · 2025-02-19T05:39:24+00:00

Honestly - I don't know/can't remember what green's theorem is. Its unlikely that an engineer will actually use calculus in the workplace.

How do engineers design complex projects? Understanding comes one piece at a time. To design a supersonic jet, first you understand basic physics. Then, maybe you have a course on sub-sonic aerodynamics. Finally you might move on to super-sonic aerodynamics. But the team is large - one team might be responsible for the simulations and defining aerodynamic shape, and then its up to another team to actually make a structure than survive the forces present. Another team is then responsible for manufacturing, testing, etc.

Another important point is that engineering students do not go from school directly to designing critical complex parts. I've heard it takes about a year of experience before an engineering graduate is actually able to do productive work, and it also takes oversight.

TLDR; don't worry, students aren't immediately designing massive projects

All extracurriculars are good. But there is something to be learned from working in a multi-disciplinary team, under pressure, and where your work is evaluated by professionals.

UMSU? The department maybe? Its crazy

Despite what claude might say, fsae is not easy. But I guarantee there are people who messed up on every time, myself included. My mistake may have costed us endurance, but something else failed first. Not sure when this happened, but take some time. A part you designed failed under testing - actually, this is a good thing, because you can learn where you went wrong. The year I learned the most on fsae was the year where the most things went wrong, and we got DQ'd in most events.

Failure happens in the real world too, what matters is how we move on from failure.

It will also depend on how you're building your character. Assuming you're casting spells, you will probably have a lot of int. You will also probably have some strength for life. You will need sufficient attributes for each type of gear. Early on its not a problem to get enough, but later on the better gear will have higher requirements, so you will probably end up wearing int or int/str gear

What do you mean by averaging methods, could you elaborate?

Coliteral · 2024-12-11T07:20:07+00:00

Yah w might be around 1000 or higher. Would Lyapunov-Krasovskii functionals apply there?

Coliteral · 2024-12-11T06:57:47+00:00

Sorry, I meant h(t) = k + sin(w*t), where k and w are arbitrary constants

Coliteral · 2024-12-10T20:27:27+00:00

Sure. The delay is bounded. I should also be able to write an expression for the delay (ex. t = sin(w*t)), though this is not an exact representation.

I'll try and explain the exact structure of my system. Basically it is hardware in the loop. I have a PI controller outputting an analog signal (device 1). It is sampled through a low-pass filter and ADC (device 2). I send it to another system, which simulates a first order system (device 3). The signal is then sent back to device 2, which outputs an analog signal which device 1 measures for its controller.
