First of all, the chapter that you were posted was taken Voltage-Sourced Converters in Power Systems: Modeling, Control, and Applications. so there are many mistake in this book; which are corrected later by the author. As a result, please follow this link to see the correntions http://www.ee.ryerson.ca/~yazdani/Yaz....
According to what you said " I have developed a simulation for vsc control in d-q frame, but it is not stable and does not work properly " you did not attache the right file.
But You can see the model that is built by PSCAD support and modify it based on your requirement. the model under name "3-terminal HVDC link with 2-level VSC terminals"
See the link below
I hope that I helped you

But the control strategy in PSCAD example is based on capacitor voltage control and not current control.
Also thanks for your valuable comment about book corrections ...
Also i have attached the file again. May you please take a look at it?
