 Hello EEVblog guys !
always thanks you so much for help.

now i activetly find book about analog computer.

i want realize control theory throught analog computer.

can you recommend book to me ?

Please let me know !

Here is a way to get a list of possibilities
https://www.alibris.com/booksearch?keyword=analog+computer (https://www.alibris.com/booksearch?keyword=analog+computer)

I like "Introduction to Analog Computer Programming" by Rummer

Here is a great site re: analog computers:
http://www.analogmuseum.org/english/ (http://www.analogmuseum.org/english/)

This is a pretty good book but pricey:

Which analog computer are you using?  I just bought a Comdyna GP-6 and it should show up in a few days.  I also built Dr. Vogler's small computer:

I also use Simulink in Matlab to interconnect blocks and form problem specific analog computers.  Problems like the Predator-Prey and Damped Harmonic Motion are easy to simulate.

Spend a lot of time at http://www.analogmuseum.org (http://www.analogmuseum.org)

The part I am still learning concerns the mathematics of scaling the problem in terms of amplitude and time.  It is discussed in Rummer's book.  I'm still trying to work through it.

Most primary texts are bound to be old, like this from 1967:

If you're willing to part with > $100, this looks good:

Thanks you a lot Always, Mr. Rstofer !

i know very well. give answer and advise - it is sometimes, tired job. but, Mr. Rstofer always give help. so, i feel big thanks to you.

finally, i got good information thorugh you ! :)

in my case, I don't know anything yet about analog computer. but I am interested about implementing of control system through analog computer.

I have attached a rather simple 2d order differential equation for a Mass-Spring-Damper problem.  Electrically, this would be an R-L-C circuit.

I like hardware so I prefer to play with an actual analog computer but Simulink is far quicker.

Here is a YouTube author with several videos re: analog computing

https://www.youtube.com/channel/UCOrVViyhnQSYiJym5ngFlNg (https://www.youtube.com/channel/UCOrVViyhnQSYiJym5ngFlNg)

In the 'Calculus' video, he gets into scaling and how the scale factors accumulate with successive integrations.
