Questions about direct torque control

I have three questions about direct torque control:
1. what is the disadvantage of DTC?
2. Is DTC popular in industry drives? I only know ABB drives have DTC control.
3. Why we need sensorless control for the control of PMSM since DTC is sensorless in nature?
Waiting for your help.
