Connected mathematics question to the simulation library blocks

Hi

I am working on a dynamic model for the induction generator which is presented in some of the mathematical differential equations. To run this model I have to connect the output and the input to some block in simulation library but I can not connect them.

Please note that I represent the mathematical equation as subsystems which has input and output

[Ameer Hamza]

Can you show the model? It is better if you attach the Simulink model file.

[Ahmad Badran]

for example I want to connect capacitor to the Vqr and Vdr inbut but I could not or input voltage source to Vds and Vqs

[Ameer Hamza]

Which capacitor or input voltage block are you trying to connect. Is it from a simscape library?

[Ahmad Badran]

yes it is

Even I have tried to connect converter blocks in simscap library but Icould not

Answer 1

[Ameer Hamza]

Simscape blocks cannot be directly connected to Simulink blocks. You need to consider several things when making a connection. A while ago, I wrote an answer to another question on the same issue. Read the answer and especially read this comment: https://www.mathworks.com/matlabcentral/answers/509668-how-to-check-the-outputs-of-the-incremental-shaft-encoder-in-simulink#comment_809244. If there is an issue, attach a simple Simulink file (.slx) with the minimum number of components which you are not able to connect.

I tryied to connect Var, Vbr, Vcr to the the two level converter but i could not as it show in attashed. I have sent the slx file as will please have a look

Hi

Thank you for help, So controlled voltage source is use for coneccting purpose as it in my case, or it has another purpose

[Ameer Hamza]

Controlled voltage sources can have several other purposes too. You need to see from block to block bases on how to interface blocks between different simscape libraries. However, I have tried to define some general rules in the comment I linked in my answer.

hi

In case I want to connect these two block what I should use in between
