SISOTOOL Installation

[Swagata12345]

Hi,
I have OCTAVE 5.2.0 installed in my computer that comes with control-3.2.0 package.

I was trying to install SISOTOOL from https://github.com/EriveltonGualter/octave-control https://github.com/EriveltonGualter/octave-control .

The target folder calls for installation of control-3.1.0 package. I was trying to install the package as per instruction. The installation is giving following error message:

When I was trying to execute SISTOOL as per help file- getting following error message:

warning: legend: specifying location with a numeric argument is obsolete and will be removed from
a future version of Octave, use a string specification instead

Swagata - i got the same results. Once complete, i no longer had access to the control folder. It appears to be deleted. I get the feeling that this tool was never completed...

Brett, You are correct. But the tool appears to be very promising. Request author to see if any update is possible. Regards,

Hello @Swagata12345,

Thank you for pointing out this error. I am setting a new environment to try this installation from scratch, and I will get back to you.

@bnourrcier, you are right, this project was conducted under Google Summer of Code, and I guess it was never updated to the main branch of the control package. I will reach out to the mentors for the project as well.

Best,
Eri

Eri – thank you for the response. Do you know why this tool (sisotool) was never added to the control toolbox? I am new to Octave but will be glad to help if I can. Thanks again!

Hi Eri,
I'm trying to install this also. Could you or someone confirm that Octave 4.2.2 is a version that the install will complete for while the Octave 4.4.0 does not correctly complete the install?

Also: is this know to work under Windows 10 or was it just tested against Octave on Linux?

Some more observations:

1. Needs 4.2.2 to load up ok.
2. Under windows G = tf([1], [1 1]); sisotool(G) doesn't make any reasonable step response graph show up. (It's blank.)
3. For operation under Ubuntu, you'll need 18.04 LTS version in order to easily get Octave 4.2.2.
4. Under Ubuntu G = tf([1], [1 1]); sisotool(G) makes a reasonable step response show up. "Architecture" is missing all of the pictures shown on the main page for Eri's work.

Hi all, I have been busy with school work and I haven't the chance to look at this in detail.

I tested under Windows 10 and Ubuntu 18.04 for Octave 4.2.2. I have updated my Octave version and I faced the same problem as you guys. I am downgrading Octave to 4.2.2 to make sure it still ok.

I understand. Please don't take my chattiness here as impatience. I just wanted to document my attempt at getting it running and what worked / didn't so it's not lost work. I've made the decision to fork over the cash to Mathworks to get the thing going I'm working on.

What you got going here is a great start, I expect. Having it around will, eventually, reduce a hurdle to teaching / learning how to build control systems on a shoestring!

No problem et all :D
ANd thank you for your feedback/contributions.

Using Windows 10 Pro, Version 2004, OS build 19041.685 I installed Octave 4.2.2 because installing SISOControl under Octave 6.1.0 failed. Under Octave 4.2.2 I got these messages:

warning: couldn't clean up after my self: Permission denied
For information about changes from previous versions of the control package, run 'news contro

I don't yet have experience with SISOControl, but I wanted to provide this information before it vanishes from my system. This might be helpful to someone. In the meantime I'll try to see if SISOControl works despite these messages.

Follow up:

I got messages like these, the last pair in a very long series. I don't know how to get around them.
