It now subracts where it should be, from where it wasn't, or vice versa. By differentiating this from the algebraic sum of where it shouldn't be, and where it was. It is able to obtain a deviation, and a variation, which is called "error"
The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position that it wasn't, it now is.
oh please god yes Joe please for the love of god put one in the ground thoomp tubes all over the world enforcing the will of the new world order headed by Elon Musk and his doppelganger Joe I can see it already glorious seriously though please put a thoomp tube in the ground
Yes! More rocket goodness! The production value on this is perfectly acceptable. Still tons of information and plenty of explanation for what went well and what went wrong. I look forward to seeing more of this!
Yes!!! Moar BPS! I 100 percent love the way that it pops out, shoots sparks and looks like it’s going to fall before the engine lights and it takes off as the cover snaps shut to keep the silo safe from the plume.
BPS, I have a PID-controller lesson learned that might be useful to you. Many years ago I worked as a flight test engineer on a (now-retired) military aircraft that used a PID controller for its autopilot. Several crashes occurred in active service, which led to our autopilot upgrade program. The crashes were due to the roll axis apparently having a "hardover condition" and causing the pilots to eject, thinking that the ailerons were locked hard to one side. Eventually we discovered that the PID's "I" integral term was "winding up" or slowly saturating. The pilots had a habit of applying sustained rudder pedal while on autopilot heading hold (to cause a sideslip to correct a wing fuel imbalance). When they released the pedal, the fully-saturated integrator took over 30 seconds to wind down - so the roll axis was applying full aileron "uncommanded" (from their point of view). In other words, they were bailing out of a perfectly good jet, because nobody understood the PID controller. The fix was simple: correct the integrator to immediately de-saturate when the proportional error went to zero. Looks like that could help you out.
ive been watching this channel since about 2 ,000 - 3,000 subscribers, and you've inspired me to learn more about model rockets. i'm 14 and currently working on a 9ft high power rocket. I think the kind of stuff your building is awesome, and good luck.
You get that brief moment of "oh no it's going to fall" where it stands absolutely still in the air before the rocket hits full power and speeds away, exactly like real silo launched missiles do. At least on the published videos. :-)
Like a lot of others have said, seeing that launch tube close over just as the thrust kicks into high gear, really adds to the professionalism of the launch :)
your videos are always interesting to me, I'm old enough to remember when our rockets were blowing up on the launch pad... and now we have SpaceX making soft landings of the boosters. that was stuff we only could dream about when I was growing up, and now, it's being done... and what you're doing is fascinating and shows that you are a very bright young man... Keep up the great work...
At first I thought that video would not be as great as previous without usual commentary, but the 1st launch drone video was just soo epic and showing the flight data and setup file was also great. Thank you for what you are doing and keep doing it becouse you are great!
You may want to look into anti-windup control. Very easy to implement. If you want to go fancy: Model Predictive Control (MPC) is way better. It controls ahead of the trajectory using optimal control techniques. Enjoy.
Awesome, just awsome.. I can't wait to show this one to my Dad.. He will absolutely love all the shots of the tube launches. He will be stunned to see all the data you captured 🙂
I think you could mount the launch tube in the center of a quadcopter, for one of a kind launch. Bonus points for catching the rocket by it's parachutes with the drone, like rocket labs is doing.
What I would find very interesting to see is the full process of the data like u showed in this video, but then using that data to improve on the vectoring system. Just the fine tuining process I think over all is always the most interesting.
I'm not 100% but i think P+D will be a better choice than P+I+D. PID you can follow the curve but delay, time constant or speed response ruin everything but in case PD it will improve speed of response, Improve Transient State characteristic, lesser time constant and BW is more. Note: Let me know your thoughts.
I would recommend starting ignition slightly before you lose all of the velocity you gained out of the tube from the compressed air. Combine the ramp up time of the motor with the deceleration of gravity to maintain velocity.
Add a little more weight in the nose, if you can. It will increase your dynamic angle of moment and improve your stability, making it easier for your gimballed motor to keep it pointed where you want it to go.
TL ; DR ignite the motor a few seconds earlier I think you waste a tiny amount of power because the engine needs to counter falling when it ignites. If you just ignite it a few milliseconds earlier, I think the rocket would still go up when the engine reaches full power, and this way you might be able to raise your apogee a few meters. If you already tried this and figured it didn't work, I would love to have some explanations (maybe in a video?)
I 100% support this decision already
I definitely agree...
Lol yes.
Drops all camera views into edit - hits publish - we rejoice!
5 min editing, job's done and back to work right away. That's the only (and the best)way to do it.
Amazing how the silo cover moves so fast before ignition
The missile knows where it is because it knows where it isn't.
By subtracting where it is, from where it was. The missile determines a deviation.
I think that's called a particle filter?
It now subracts where it should be, from where it wasn't, or vice versa. By differentiating this from the algebraic sum of where it shouldn't be, and where it was. It is able to obtain a deviation, and a variation, which is called "error"
The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position that it wasn't, it now is.
Don't forget that the missile, if it isn't sure where it is, it always knows where it isn't or where it was, within reason.
can you PLEASE put one of these tubes in the ground
This.
.
I was gonna say put one on his shoulder... 0_0
Legendary idea
oh please god yes
Joe please for the love of god
put one in the ground
thoomp tubes all over the world
enforcing the will of the new world order
headed by Elon Musk and his doppelganger Joe
I can see it already
glorious
seriously though please put a thoomp tube in the ground
only 299,000 more feet to go now..
he went less than 200 feet on an F15! how about we try for high, before we try for REAL high
Yeah, why does it quit after a relatively short ascent? Is it more about the tube and not so much about the general performance of the rocket?
love how the onboard was kind enough to pitch over to give us a nice view of the launch site at apogee
one day this guy is going to put himself in the orbit and post a tutorial for it.
Lmao yes
@@Wilge_Zomer mate what did you forget here... Never expected you to watch these too
@@The_RoboDoc dude, everybody with a remote interest in rockets watches Elon's clone's vids
@@Wilge_Zomer Yeah, you are right

Oof its the real guys from copenhagen suborbitals nicee you guys are doing a really good job
Why thank you!
I always back of you guys @copenhhagen Suborbitals.
The thing I like watching most, is the tube door closing.
Joe has mental breakdown after realizing he didn't have to meticulously edit all his past videos, and that we just want to see rocket go up
My favourite thing about this is how the thoomp tube closes perfectly just before the thrust really starts. Makes it seem so much more legit.
I love how the cover closes to protect the tube.
I finally get why your components are export controlled
Yes! More rocket goodness! The production value on this is perfectly acceptable. Still tons of information and plenty of explanation for what went well and what went wrong. I look forward to seeing more of this!
Yes!!! Moar BPS! I 100 percent love the way that it pops out, shoots sparks and looks like it’s going to fall before the engine lights and it takes off as the cover snaps shut to keep the silo safe from the plume.
Awesome. I like the timing on the hatch closing, and the rapid reusability.

I'm loving this new format, I hope it stays like this in the future
What about a missile-intercept system, perhaps like THAAD, Patriot, or Iron Dome? You could sell it to farmers who have turkey vulture problems
Rip the turkey vultures.
Wait actually no screw the turkey vultures.
Also add S-400
And so the experiment begins ;)

I love how synchronised the engines ignite and the silo door closes

Possibly the coolest rocket launch on RUclips !
I very much like this video format more! I love seeing the technical stuff
That was awesome to watch! I bet it was super satisfying to have 2 successful launches and to get so much usable data back :)
Thanks for showing us how the program works & the data!
Being able to view some of the flight data was a nice addition.
Really cool. its nice to have a video with just the differents camera views

This is a good idea to do videos whenever. it brings more excitement to the channel
Awesome stuff, Joey B! This is the BPS we came here for! Launch launch launch!!
It's so satisfying that the tube closes just before the rocket fires
Massive achievement. Thanks for explaining things just enough for us non rocket experts too.
This is so cool, and 5 min after i watched you last videos say you are not posting long videos any more :) I really enjoyed the addition tech detail

That was fast. Nice to see new video here
Nice cold launch, great works
Awesome!!!! Gorgeous launches, spectacular ignition timing!
HUGE!!!! Thats so sick man!! Reallly admire your work!! Keep it up!
you know you are early when there are more likes than views
congrats man
I particularly enjoyed seeing all the numbers and graphs.
Thank you for posting your videos, enjoy looking at them all the way from Perth (Australia)
Thanks for showing the vehicle data, it was interesting
Really cool to see all the flight data!

So awesome dude. Keep up the good work. P.S. love the last decision of yours... publishing everything
Awesome work Joe, This is still quality work, it's just clearly focused on the rockets, instead of cinematography.
This is so amazingly cool!!! I've always wanted to do something like this!
Yes.
Enjoying your content from Germany 🇩🇪 huge fan 😊
Joe, you have shown us a LOT of failed launch and landing attempts in the past, this one you NAILED! Congrats!
Add a little more weight in the nose, if you can. It will increase your dynamic angle of moment and improve your stability, making it easier for your gimballed motor to keep it pointed where you want it to go.
That is a really cool way to launch a model rocket
I hadn’t noticed the rocket labeled “” before. Very nice! (If the “Dirt” end is pointing at the sky, you will not go to space today.)
Awesome! Loved the video showing the Roadster!
BPS popping off today
and yes, we fully support the "throw the vids up if you don't feel like making a huge production out of it"
a 360 camera on a rocket could be really cool
This is the video cocaine we want ,thank you for supplying our addiction.
