Dual Motor Control Labs - not much directions/explanations

Other Parts Discussed in Thread: MOTORWARE

I want to be able to control two motor at the same time from one TI processor. So, I started looking at Lab 6e, Lab 10d, 

Lab 6e - Dual Motor Sensorless - It says Sensorless, , I was expecting it to be similar to Lab 4, Lab 4a, Lab 5a, but for 2 motors. is it just current / torque control lab ? But I dont see a way to tune the PI gains for the current controller. Please help. There is also no writeup, directions for the Lab 6e, just the code which is a very different in architecture compared to rest of Motorware labs. So, this will need me to understand and locate every variable again from scratch. Even if i use spintac controllers , the current controller used to be just a PI controller and so the first thing i had to do was tune that before moving ahead with spintac velocity or position controllers. So, I am trying to do the same first with Dual Motors.

Lab 10d - Dual Motor Sensorless Velocity Control. Is this similar to Lab 5d, lab5e? but for 2 motors

Lab 11d - Dual Motor Sensorless Velocity Control. - how is it different compared to Lab 10d? both labs have the same names. 

Lab 12c :  Dual Motor Sensored Velocity Control. Is it similar to Lab 12b, but for 2 motors.

Lab 13f : Dual Motor Sensored Position Control . Is this similar to Lab 13b ? but for 2 motors

    Lab10d has an in-depth write-up that accompanies the lab in MotorWare 17. InstaSPIN-MOTION labs 6e, 12c and 13f were all based on lab11d, which has no write-up. Lab11d is based on the simplified code structure of lab11. There is no acceleration variable for this lab (11d), which means speed changes are applied as step inputs. We decided to create a new project that included the full CTRL structure available in InstaSPIN-FOC labs, which we released as 10d. We do not plan to release any additional documentation for lab11d or the MOTION projects that followed; if you would like to know more about their implementation, please review the source code.
