1. Sobre a velocidade de convergência da filtragem adaptativa IIR. / On the convergence speed of IIR adaptive filtering.
Adaptive filters with infinite impulse response (IIR) can replace with advantages the ones with finite impulse response (FIR). One of these advantages is the reduced number of parameters which leads to a smaller computational complexity giving similar responses. However, the use of adaptive IIR filters has some pratical issue, being the most prominent its sl

2. Frequency estimation in power system through adaptive filtering / Estimação da freqüência em sistemas elétricos de potência através de filtragem adaptativa
This work presents a method for frequency estimation in power systems using adaptive filters based in the algorithm of least mean square (LMS). The analysis of the power system is made through the conversion of the three-phase voltages in a complex signal with the application of alfabetatransform, whose complex form was directed to the algorithm of adaptive
