This work presents a strategy of adaptive PI control based on Gaussian profile curves, where the gains are functions of reference error. The strategy was applied in energy conditioning systems. Firstly in a phase-locked loop (PLL) for single phase systems, where two techniques were tested, the pPLL and DSOGI-pPLL. After it was applied in a voltage and current control of single-phase parallel active power filter. The adaptive control was able to improve the system performance and also decrease the total harmonic distortion of compensated current.
