Direct Torque Control vs Sensorless Vector Control

[marke]

Hi

 

From what I hav seen, there are two types of technology applied to modern speed controllers that are above the standard V/Hz model.

There is the Direct Torque Control and there is the Sensorless Vector Control.

Both claim to do the same thing, but use a totally different algorithm to achieve the results. This is not just the usual play on words, they actually are quite different approaches to achieve the same results.

 

I am interested in the pros and cons of both systems. Where would you use one, and where would you use the other, or are they totally interchangeable.

 

Thoughts and experiences??

Best regards,
