Nice Job on this program. I just downloaded this a couple days ago and I've been trying to expand upon it to plot the Root Locus as well and I can post the code when I complete it if you would like.

I am running into an issue with a couple Phase plots. Please see the attached pics. I have a discrepancy between Matlab/Solutions Manual & the program and I need a little help trouble shooting. As you can see, there seems to be a vertical asymptote.

the graph is right on Prime..... check it with trace function.
Matlab is playing some tricks here...... at angle 180degrees they flip to -180degrees to get that continuous graph.

BODE(0.001,10000,[-10 1000],[1 1 0]) on Prime:

What's up with that? Issue with Nyquist plot?

nothing wrong with the plot....on Prime
try your plot in Matlab....and box zoom Prime plot : Same same.

Thanks for the quick reply! You're right, you need to know where to look at when it comes to nyquist plots...


I've been playing with Octave on my phone, and narrowing range to w=5:0.1:200 and nyquist(gh,w) I get:

   


I don't understand Wolfram's output, the interception should be at -10 not at -3.5 as shown on the attachment. Anyway, sorry for the offtopic.

Info text seems to be corrupting a lot here, that's why i removed it.
Thanks... i inserted it back to the App

RE: Bode/Root Locus/Nyquist/Nichols...App{update 09JUN2016}
Hi,

First of all thanks for your program, I'm an engineering student, I've an exam next week and I don't understand how to enter the transfer function and start the root locus. I tried to write the examples you gave but the app doesn't start. So if you could help me, it would be fine.There are some screen captures attached.



[Image: Sin_t_tulo.png] [Image: Sin_t_tulo.png] [Image: Sin_t_tulo.png]

I followed all the instructions you gave and when I checked the program, I got a syntax error in line 45 and it appears as I attach.

Hi,

I've tried to install the application, but got error "Cannot send content to other HP Prime. Please update firmware using Connectivity Kit". But I am using version 2015-6-17, which is the last version from hp. How to solve?

Thanks
Tom

check your update... if possible try updating the Prime again, and reinstall the App.
Or flash your hp prime.

RE: Bode/Root Locus/Nyquist/Nichols...App{update 09JUN2016}
Hej guys!

Thanks for writing this awesome program that I would love to test in my engineering studies :)

However, I have issues installing and I find little solutions online...

What I do: I download the zip with the latest version from you and extraxt it. Then I open up Connectivity Kit and drag the "Bode Plot.hpappdir" onto the lower left pane. Thereafter I drag the folder which is created onto my calculators name in the top left pane. I have also tried dragging the folder directly onto the calculator name.
It only seems to install the files "thumbs.db" and "icon.png" but not the rest. When I try to compile it as u describe the program only contains

EXPORT Bode_Plot()
BEGIN

END;

and nothing more. I have the latest firmware and Connectivity Kit... I have tried updating both and do this all over again without results. I regret to say I find the community somewhat confusing, can you help me att all getting your app to work? :)

Thanks in advance!
