How do I analyse a feedback linearised control system with a large number of internal dynamics?

I have a MIMO system of order 14 with two inputs and two outputs. I want to apply feedback linearisation to control it. I have attempted this, and as a result I have a FBL system with a combined...

In a stator flux oriented control scheme for an induction machine, why is Vds=0 and Vqs= Vs (terminal voltage)?

In a dq reference frame rotating at synchronous speed: If the d axis of an induction machine is oriented with the maximum of the stator flux, how does it result in the stator q axis voltage (Vqs)...
