Error in port widths or dimensions.

Dear all;
this error message is appearing when i’m running the control model (like a control model in Fig. 3.6_page 26 @ “Advanced Control Design for Wind Turbines - Part I: Control Design, Implementation, and Initial Tests _ A.D. Wright and L.J. Fingersh” )

Can you help me to fix it , Please?


I am not a Simulink modeling expert, but the error message says mux1 has 54 outputs and the FAST S-Func is expecting 55 inputs. I’d take a look at Mux1 and see if you’re missing one.

Thanks a lot Bonnie.Jonkman
