# confusion regarding QNET VTOL(Vertical Take off and Landing)

I was reading a manual about QNET VTOL and i came across a block diagram(shown in attached snapshot)

In the explaination of diagram, manual writes that

The VTOL device is broken down into two subsystems: the voltage-current dynamics of the motor and the current position dynamics of the VTOL body. The cascade control implemented in the VTOL trainer is depicted in Figure 10.2 below. A PI current controller, the inner loop, is designed to regulate the current inside the motor according to a desired current reference. This current reference is generated from the outer-loop controller: a PID compensator that controls the pitch of the VTOL trainer.

Where are the two subsytems in block diagram,i think one systems is motor represented by the one with denominator Lms+Rm,if yes how/where other system is represented?

After locating the two subsystems in block diagram,please also mention their working/aplication

Only the motor control is shown in detail. The pitch dynamics of the aircraft only show up as $$\P(s)\$$.
