Thanks Peter that will be fine. My rethink on how best to avoid flux wander is to have balanced 360 degree cycles. I know there will need be a step changes during ramp up etc but after an increment step the increased amount of the next 180 degrees after the step change should be reflected in the next/following 180 degrees, so I am very happy with 50 Hz control & steps. I am aware that corrections to output loads etc may be slightly slower but I am happy to accept that.
I have also decided that if this experiment does not work/improve the grunt I will just go with the slower ramp time and be happy with the quieter grunt.
