Abstract: In this paper we show the main results obtained when
applying the average theory to Zero Average Dynamic control
technique in a buck power converter with PWM. In particular we
have obtained the bound values for output error and sliding
surface. The PWM with centered and lateral pulse conīgurations
were analyzed. The analytical results have conīrmed the numerical
and experimental results already obtained in previous
publications. In the last section we have generalized the theory
for any second order system with relative degree 2, which can be
controlled with this technique.
