  • Abstract
    A time-localised iterative least square (TILS) based predictive zero-crossing detection (ZCD) algorithm for signals with slowly varying amplitudes and phases has been proposed in this paper. Useful for digital implementation, this technique predicts the zero crossing instant in advance so that further control decision based on ZCD could be performed without delay. The analytical formulation has been verified through experimental results.
