Digital sliding modes and quasi-exact tracking discrete-valued signals

Abstract

This work initiates study of level quantization effect in the digital implementations of sampled-data systems featuring real sliding modes of first and second order. The effect of rounding midtreat quantizer at the input or in the loop of a feedback control system of relative degree one is analyzed. Novel concepts of regular digital codes, relative degree of digital signal autocorrelation, discrete-level and digital sliding modes are introduced
