Hello all,
I am making PMSM modeling with simulink.
I faced in some error with this picture.

Hello Ankit,
I tranformed my simulink data into 2018b version.
Please check and review it.
I would appreciate if you could give me solution.
Thanks

You had two issues. One was the integrators in Current_Controller were implimented using the Memory in the feedback path causing an algebraic loop. I simply moved the Memory into the forward path to remove this error message.
The second problem was an error message from the compiler about DQ_ABC/Matlab Function1. I had to correct this by specifically defining the size of the input "u" using the Ports and Data Manager. It was strange that the compiler only complained about this specific function.
