Unable to obtain dropdown menu in Control System Toolbox

3 views (last 30 days)
Hi,
when in Control System Designer (opened via sisotool(sys) command on the command window), I try to add a new plot for a step forcing function (New Plot->New Step); after a new window (called "New Step") pops up, I choose from the dropdown menu "New input-output transfer response". This should give back some other dropdown menus but they do not appear to me: as soon as I select the option, error lines are displayed in the command window. I have attached them below.
I have tried to:
-reinstall Control System Toolbox add-on
-reinstall MATLAB (I have also tried downgrading from the 2022a version to the 2021b)
-remove all add-ons except for the Control System Toolbox one
Unfortunately neither options seem to work for me: therefore I'm asking help here.
Thank you in advance for your time ;)

Hello Aniello,
It seems you're experiencing some trouble with the Control System Designer application. I've tried to replicate the problem on my side but haven't encountered the same issue.
I recommend updating MATLAB to the most recent version to see if that resolves the problem. Alternatively, you can open the Control System Designer by using the command `controlSystemDesigner` instead of `sisotool(sys)`. When I select the 'New input-output transfer' option, I am able to access the additional features.
If the problem continues, I suggest reaching out to the MathWorks Technical Support team for assistance. They are well-equipped to provide the necessary support.
Thanks and regards,
Balavignesh
