2015b: I am attempting to autocode the Simulink Library Block PID controller, but I get an algebraic loop error. Please refer to attached PDF.
Thank you for your help. Esmael

There is no attached PDF. Instead use Simulink's debugging feature (sldebug) to highlight the algebraic loop. I would assume you need to insert a unit delay on your measurement feedback.
