Ridge, AN and McMahon, RA and Kelly, HP (2013) Sensorless commutation of a two-phase linear machine for marine renewable power generation. Proceedings of the 2013 IEEE International Electric Machines and Drives Conference, IEMDC 2013. pp. 1023-1030.Full text not available from this repository.
A sensorless scheme is presented for a two-phase permanent-magnet linear machine targeted for use in marine wave-power generation. This is a field where system reliability is a key concern. The scheme is able to extract the effective inductance and back-emf of the machine's phases simultaneously from measurements of the current ripple present on the power electronic converter. These measurements can then be used to estimate position. An enhancement to the scheme in the presence of spatially-varying mutual inductance between phases allows more accurate and reliable tracking from indutance-based measurements than would otherwise be expected. This scheme is able to operate at any speed including, critically, when stationary. Experimental results show promise for the scheme, although some work to reduce the level of noise would be desirable. © 2013 IEEE.
