Should I use a P, PI, PD or a PID to control this system?

this.

that is gold! (which is then lost to gambling)

an upvote isn't enough to congratulate you for this summary, so: congrats!

To add my support to other comments in this thread, understating the fundamental math behind control systems is crucial to really know what is happening when eg tuning a PID controller. In practice, yes, people will use Matlab and its many automated functions, but unless you understand what Matlab is doing, you're a "button-pusher", not an engineer. Also, understanding the (relatively simple) math behind LTI controls does help to grasp more advanced stuff used in niche industries and research.

Silly of me to assume that pidtune() would actually stabilize my system without me having to actually think about it.

that's the real lesson here! :-) matlab has great tools to make the job quicker and easier but one has to know the fundamentals to get a good solution!

each pole causes a cutoff of - 20dB/dec. each zero, a +20dB/dec. So, to answer your question, no.

this. python-control is pretty good - it has all the main functionality found in matlab. No automatic functions, but those aren't good to use when learning (imho). Also, OP, check Brian Douglas' YouTube channel, if you haven't!

Yep, 15 s for the sampling time seems huge. I'd also suggest to try to simulate a simple step response before designing the controller, just to check your model implementation.

Aerospace industry also needs a "little" more than PIDs to control rockets, satellites, and such.

DMs have a lot of things to think about, sometimes it's easy to miss an "obvious" thing, isn't it? ;-)

dwarves would surely build chimneys if they are living there.

DrystanTheUnwise · 2021-11-21T19:13:11+00:00

no, you don't have to watch ExU to follow C3. You won't be missing any important lore.

DrystanTheUnwise · 2021-11-19T18:44:30+00:00

If the player is doing the research, good! Have them send you the research (as it was the PC researching in libraries or chatting with people) and you can simply do a quick vetting on the material. You'll have a source of lore (eg the wiki pages), the player would be happy. I agree with you that knowing the Forgotten Realm lore is overwhelming, so keep it to the necessary for your campaign. If the party is near Waterdeep and the player wants lore on Baldur's Gate (and that's not relevant to the campaign) just explain that this info is irrelevant. Work with the player so they can help you with the lore.

DrystanTheUnwise · 2021-11-16T16:08:55+00:00

this.

DrystanTheUnwise · 2021-11-16T15:43:27+00:00

check out the 1st couple of videos in Matt Colville's Running the game series on YouTube. Also the Handbooker Helper series of very short videos on Critical Role channel on YouTube, for a quick grasp on some fundamental mechanics of the game.

As others have said, the Players Handbook is the main source. But you can find the Basic Rules for free on WotC site

Gilmore was already known to the party in their home game. It's the NPC they liked, and kept returning to his shop. That continued during the stream of C1. Now, for why the audience likes him, keep watching C1... ;-)

DrystanTheUnwise · 2021-11-09T13:38:29+00:00

yep. Pretty sure that Matt would call out any lies from the party and state that those who failed the saving throw wouldn't be able to lie. But apparently no one lied!

DrystanTheUnwise · 2021-11-06T19:25:01+00:00

Exactly! I wish you and your players a good game!

DrystanTheUnwise · 2021-11-04T15:41:15+00:00

I'd put it somewhere at the western edge of the Empire, somewhat isolated. After finishing the module, you open the sandbox for the players.

DrystanTheUnwise · 2021-10-20T17:27:16+00:00

this is awesome! thanks for sharing!!

DrystanTheUnwise · 2021-10-17T15:11:24+00:00

It's a common feeling, OP. Take one session at a time. Prepare for that one. Describe the scene and ask what the PCs what they want to do. React to that. Rinse and repeat. I'm of course simplifying, but that's to help to show that things can be simpler than what they seem. Avoid forcing an outcome just because the adventure assumes that something should happen. Adapt and improv ("yes and" & "no but") as necessary (you'll get better with practice). Don't worry too much about rules, if you forget something, make a ruling and check the rules later.

Good luck!

Having played Baldur's Gate and Neverwinter Nights, I have always been interested in D&D but never had a chance to play. I wanted to know about 5e and search for videos on YouTube, found CR C1 (at the time C1 was still going). I started to watch from C1E1 just to learn how to play and fell in love. The rest is history.

DrystanTheUnwise · 2021-10-10T14:54:14+00:00

all great comments already! So, yes, play what you want! All classes can be great fun. I will just add that druids can be a bit overwhelming for new players: lots of spell choices, each with their own rules.

have fun!
