Because input to bottom block is an array of two signals [Ld Lq], although only one line is visible.

The relevent parameter Ld Or Lq is chosen based on input to the multiport switch.

  • For d-axis voltage equation, this subsystem does Lq/Ld
  • For q-axis voltage equation, another subsystem does Ld/Lq

You may find the math on the following page.
