	%X The operation of grid-connected inverters necessity a
single-phase phase locked loop (PLL) is proposed in this article to
accurately and quickly estimate and detect the grid phase angle. This
article presents the improvement of a method of phase-locked loop.
The novelty is to generate a method (PLL) of synchronizing the grid
with a Notch filter based on adaptive fuzzy logic for inverter systems
connected to the grid. The performance of the proposed method was
tested under normal and abnormal operating conditions (amplitude,
frequency and phase shift variations). In addition, simulation results
with ISPM software are developed to verify the effectiveness of the
proposed method strategy. Finally, the experimental test will be used
to extract the result and discuss the validity of the proposed algorithm.
