Query: Simultaneous iterative learning control of mode entrainment and error
  field   It is shown that static error fields (EFs) can severely limit the maximum
rotation frequency achievable in mode entrainment by applied rotating fields.
It is also shown that the rotation non-uniformities caused by an EF can be used
to diagnose and correct said EF in real time. Simulations using typical DIII-D
data show that this can be achieved within a small number of mode rotation
periods by an iterative learning control algorithm. In addition to rapidly
correcting the EF, this gives access to high entrainment frequencies that would
not be accessible otherwise, and paves the way to rotational stabilization and
improved mode control.
