Speed or torque control at low speed without a sensor

I did some analysis on an induction motor some years ago re speed or torque control at low speed without a sensor. I concluded that there was nothing to sense and that it could not be done. In the last twenty years I have seen some improvement in sensorless control, but have not seen anyone do it at zero speed. I build motion bases using induction motors as servo motors, and I do get full torque at stall with a V/f drive using a feedback pot for position control.
