Multiphase electric machines can provide significant benefits over
conventional three-phase machines. A drawback to multiphase machines is
that they are known to have problems with stator current harmonics. The
harmonics can be eliminated by various current harmonic control methods.
However, there appears to be no clear agreement on the most suitable
method for multiphase machines. This paper aims to compare different
current harmonic controllers in terms of stability and performance under
model uncertainty. A detailed theoretical analysis of the harmonic
controllers is given by taking a modern multi-input multi-output
approach based on a structured singular value analysis. Further, the
performance of the harmonic controllers is studied with experimental
results from a dual three-phase permanent magnet synchronous machine.
The analysis and results of this paper show how to design robust
high-performance current harmonic controllers for multiphase machines.
