Ответитьawesome
ОтветитьThe example about the calculater is flawed because the law states that anything that can go wrong and a calculator is not made up of materials supporting spontaneous combustion
ОтветитьReally great video, explained in an easy way.
ОтветитьI’m on the path to become a control/PA engineer and this video excites me!
Cheers from Japan.
You can work and research Process Control following the path of Electrical, Computer, Chemical or Mechanical Engineer, each with their own specificities. It's a tough field, where different engineers need to talk to each other to make it work (especially in the chemical industry!!)
ОтветитьSweet, I didn't have to go through my assigned reading because of this haha
ОтветитьProcess control will be vital tech as related ( peripheral ) technology when we use AI as a main ( core, hub ) technology.
It is important for us not to create the worst threat to humanity 😱,
as well as biotechnology ( or bionics ) or applied informatics to help AI save the human civilization 🌈.
I was reminded that technology is a double-edged sword and the more it’s useful, the more it must be treated carefully.
just stay out of my right half plane
Ответить"it's controlled variables"? Keep paying attention to your writing, people! ;-)
ОтветитьImportantly, the 1st amendment to Murphy's law is ..."at the worst possible moment."
ОтветитьI miss hank and john ...
ОтветитьAlways assume imperfections in your sensors. I work with drone software. One of the research groups we work with has drones that use barometers to estimate their altitude. They figured it was a great idea to figure their drones landed when the barometer says the height is 0, and completely shut off the motors. Unfortunately, barometers aren't super accurate, and also can't measure the absolute height above ground. The drones ended up falling down a meter or so, and breaking some parts.
Ответитьwhy are crash course views less that stupid meme compilations ?
ОтветитьWhat about PID loops?
ОтветитьHey Hank and John,
My name is Angela and I'm a huge fan of everything you do. I've read all John's books (waiting for xmas to read hanks,) listen to the pods, and of course LOVE vlogbrothers. I'm a musician who just recorded my first EP, but am of course still learning. I was wondering if there was a possibility you could do lessons on music theory. It's really interesting but no one has been very good at explaining it, therefore it's still very confusing to me. Thank you so much!
U r big gae
ОтветитьСделайте пожалуйста видео ускоренного курса про Украину, безумно интересно что скажут об этом ваши историки
ОтветитьI did a module on Control Theory as part of my nuclear physics degree, and as Lewis Foster says, PID is important. I thought it might interest people to have a practical example from that:
In order to keep a nuclear reaction steady, you want a set neutron flux in the reactor, one way to control that is with the control rods. These are materials that absorb neutrons (In a PWR you can also add boron to water, in the form of boric acid)
Whatever you do as an intervention, there is always going to be some lag between action and effect
Now, let's say you get a reading that's too high, so you lower the control rods/add more boric acid, you go for a linear approach, so your intervention is directly proportional to your intervention. With this approach, you'll typically overshoot and end up with too low a neutron flux, so you then raise your control rods/take some boric acid out
Well done, you now have set off an oscillation in your neutron flux, and with a proportional/linear response that can quite easily be one that grows with each iteration. For obvious reasons, that is not a good thing to happen in a nuclear reactor.
So you use an integral response to that initial deviation. I find it easier to think of this next bit like it's a mechanical system, with a pendulum, with that initial deviation from your norm being analogous to someone pushing your pendulum. You want to dampen that oscillation so it goes back to being steady, which is where an integral response comes in. You want a response that perfectly dampens that oscillation in the minimum possible time, not one like the linear response which is almost like your pushing it as it comes to the end of its swing
(Note: It's been a while since I've last done this, I might be a little off in places, and I certainly can't remember exactly how to explain how the integral response works in detail)
You bet you gorgeous dark eyes, Murphy's law rules!!
ОтветитьMurphy's Law: if something can go wrong, it will.
Murphy's Second Law: if more than one thing can go wrong, the thing that causes the greatest damage will go wrong.
Murphy's Third Law (also known as Sod's Law in Britain): Murphy was an optimist.
By limiting yourself to the first law, you kept it at a nice and basic level. I expect a separate episode on the other laws!
Thank you!!!
ОтветитьHey just wondering if u can make a video about cowboys era or if u had it already lmk i would like to check it thanks
ОтветитьTranslation to Arabic please
ОтветитьI think you did very well to explain this simply.
Great work, I can send this to everyone who has no idea what I do. 😂
cheese heads
ОтветитьAnother episode about a subject from the field of chemical engineering. Most episodes so far are about chemical engineering.
ОтветитьSo I can't skip ads now? Ok, wow YouYube
ОтветитьWisconsin thumbnail?
ОтветитьThe engineer cleaning up the spilled milk was crying. She should know that's nothing to cry about... Nice joke, Thought Cafe.
ОтветитьFor a crash course on cheese, watch “Dairy is Scary” on yt
ОтветитьTELL ME HOW TO COMPUTE TRANSFER FUNCTIONS!
ОтветитьAs obvious it might be to "decrease steam flow if something is too hot" it's not always the case. In reality steam is generated somewhere using the power of either engine that is cooled by this very same oil or a battery, that - guess what - is charged by the same engine..
I think it also should be mentioned that the whole process operates under assumption that a) desired behavior is at least marginally stable b) either globally stable or at least has a decent stability region
I don't know about spontaneous combustion, but more than one calculator has burst into flames due to my actions.
ОтветитьOmg, marry me
ОтветитьEvery time I see people with cheese on their heads I remember GB Packers fans
ОтветитьControl Systems Engineering is by far the most interesting part of Mechanical Engineering
Ответитьoddly now I want to hear Dr. Shini Somara do the audiobook version of Ignition by Clark on rocket propellants
ОтветитьI like this video a lot. I'm thinking about how this applies to software development and specifically test-driven development
ОтветитьMention hunting, where the controls keep pushing the system too far in opposite directions.
ОтветитьCheese heads! Go Packers!
ОтветитьNice! I'm taking a program at College called "Instrumentation & Control Engineering". We learn all about a process (Water tank, DP Transmitter, Rotameter, etc) and have to calibrate it in various situations and in many different ranges (mA or psi). Most people have NO idea what it is I'm studying when I try to explain it. This video is helpful.
ОтветитьSwiss is a nasty cheese I said it fite me
ОтветитьShe's a cool host. I like her. Keep her around and get her more screen time.
Ответить😍😍😍
