DTC control of a PMSG?

DTC control of a PMSG?

DTC control of a PMSG?

(OP)
Greetings,

I'm currently working on a project that requires a direct torque control of an electrical machine that operates in both generator and motor modes.  Currently this involves an induction machine with controlled slip, however do to weight and MTO restrictions a permanent magnet synchronous machine is being looked into. The application requires a DTC type of control with reasonable low amount of harmonics but can this even be done with a PMSG?  I know there are ways of doing this when the PMSG is in motor mode but what about generator mode?   If this can be done what kind of inverter would be the simplest to use?  I've done a lot of research on DTC for induction machines and have experience with them but I can't really find anything for PMSG that have DTC.
