In the model I have attached herewith of "Grid Converter Implementation in a wind turbine based on Doubly Fed Induction Generator" if I want to get output on correspondence with voltage across capacitance between two bridge rectifier which is Vdc, how can i implement these in the controller of grid side? I just tried myself as i marked in the controller(Right hand side of main diagram,Untitled1.jpg and grid side controller,Untitled2.jpg).I tried to work on the basis of following link

The measured DC-link voltage, Vdc, is connected to both Vdc and Vdc_reference. This is not correct. Ther reference is the setpoint you want to track while Vdc is the measured value. The controller is then trying to follow the reference.
