SimPowerSystem block Asynchronous Machine SI Units

I am using SimPowerSystem block Asynchronous Machine SI Units. I want to analyze this block.In option "Look under the Mask" there are many subsystems.There are many parameters in those systems like SM.Tb1, SM.Rr, SM.p etc. What is SM here? Where to get details of these parameters?? Thanks

Right-click on the block, select "View Mask..." and browse to the initialization pane. You will see that SM is a variable returned by a call to the utility function "powericon". You could potentially run the same command manually and supply all necessary arguments to get the value of 'SM'.

Thanks a lot dear. But I am still confused where to are variables like SM.p, SM.web, SM.Rr, SM.Lr etc

[Kaustubha Govind]

In this case, SM is a structure that contains fields like 'p', 'web', 'Rr', 'Lr', etc.

[Ahsan Naeem]

But I cant see these fields. Please help me to find them...

[Kaustubha Govind]

How did you get the value SM?

[Ahsan Naeem]

Actually I want to know where to get all these parameter values... Like SM.ctrl and many other...

[Kaustubha Govind]

Isn't that exactly what my original answer addresses? View mask->Initialization pane on the block to see the command that you need to run to find the structure SM. If that didn't work, please post the exact error messages if any.

i run the command manually but i get some errors.i think that's because i don't have the correct value in some arguments. Could you please tell me what value should arguments such as RotorType(for Squirrel-cage), ReferenceFrame(for stationary), and other arguments that don't have values that are numbers,have?thank you in advance.

[Kaustubha Govind]

aletsoup: Those are likely all mask variables - look at either the Mask Initialization or Parameters to see how those variables are defined.

Kaustubha Govind: Thank you for your help, and i tried with your way, but it still get some error. Actually i am fighting with the model of Synchronous Machine pu Fundamental, and when i run powericon manually, it keeps telling me some variables are undefined, such as "Units", which can be found in "Parameters &　Dialog" but cannot get the value, so please tell me how to get the value of those popup variables, thanks a lot !

Actually I want to verify the model with equations given in Bimal K. Bose...

has anyone been able to run powericon successfully from the Matlab command window? after copying values from the PMSM mask initialization and parameter tabs to make sure the arguments are valid (including MechanicalLoad)- this is the error I receive:

Error using SetInternalModels (line 124) Scope block does not have a parameter named 'MechanicalLoad'

Error in PMSynchronousMachineInit (line 11)

Error in powericon (line 99)
