2F Filter Elimination for Railway Applications

Abstract

The objective of this MTh is to analyse the mechanism of the beat phenomenon generation and to develope an alternative solution to avoid the LC lter. The analysis consist on check how the system behaves facing different modulation strategies with the LC lter and removing it. Then several beat-less control schemes are discussed without using any kind of fi lter. Finally, the validity and effectiveness of the adopted beat-less control strategy are veri ed with simulations
