Description
Summary:Purpose - To propose trigonometric interpolation in combination with the sliding-surface technique for modeling rotation in electrical machine models discretised by the finite integration technique (FIT).Design methodology approach - Locked-step, linear and trigonometric interpolation techniques are developed for coupling the stator and rotor model parts of an electrical machine model.Findings - Linear and trigonometric interpolation should be preferred over the locked-step approach. Three-machine models with sliding-surface coupling discretised by the FIT result in efficient and reliable models.Originality value - The introduction of sliding-surface techniques in the FIT, the trigonometric interpolation used in combination, the application of the FIT for simulating electrical machines.
