neural network to simplify induction motor control
AC motor speed and torque control can be quite complex. Field oriented control offers the highest level of control and is probably more complex than other methods, but sensorless control methods that seek to approach the highest level of performance can also be quite complex. I don't believe that AC motor controls on the market use neural networks.

There is a large market for induction motor speed and torque control. There is probably a small part of that market that requires position control.

There are recent papers about neural networks used in AC motor control, not necessarily field oriented control.
