Abstract: Abstract Step skew products with interval fibres and a subshift as a base are considered. It is proved that if the fibre maps are continuous, piecewise monotone, expanding and surjective and the subshift has the… read more here.

Abstract: ABSTRACT We study step skew-products over a finite-state shift (base) space whose fibre maps are injective maps on the unit interval. We show that certain invariant sets have a multi-graph structure and can be written… read more here.

DOI: 10.1109/tec.2016.2620476
Abstract: This paper proposes optimal step-skew methods for cogging torque reduction in interior permanent magnet (IPM) machines. First, a vector diagram method is employed to analyze the principle of a conventional three-step-skewed rotor, followed by two-dimensional… read more here.
