syms K T
H=syslin(' c ',K/(s*(T*s +1) ))
When I run this code I get errors complaining about syms, I can't find it in the list of functions on the help. I did find an online reference telling me that it is part of the ATOMs addendum to the Scilab environment. Looking at ATOMs I find a whole slew of tools that can be added, and I have no idea which one and whether this is even worth the effort. Maybe if I understood the code a little better I could find a workaround syms. It looks like the original intent of the syms K T line was to define 2 variables of some sort. Then they are used in syslin to define a linear system, which is then used by nyquist. I have also seen this same sort of thing used in evans for a root locus plot. Can anyone explain how K and T are used in this code to get a nyquist plot?
As reported earlier and addressed, we have problems running code with 'syms' command. Can you try this and let us know the results? https://scilab.in/scilab-symbolic-toolbox Be informed that the toolbox will work only with the mentioned system specifications. Looking at the code, I am assuming that you know what K and T are with respect to control systems.
