Power electronics plays an important role in controlling the grid-connected renewable energy sources. This paper presents a novel adaptive neuro-fuzzy control approach for the renewable interfacing inverter. The main objective is to achieve smooth bidirectional power flow and nonlinear unbalanced load compensation simultaneously, where the conventional proportional-integral controller may fail due to the rapid change in the dynamics of the highly nonlinear system. The combined capability of neuro-fuzzy controller in handling the uncertainties and learning from the processes is proved to be advantageous while controlling the inverter under fluctuating operating conditions. The inverter is actively controlled to compensate the harmonics, reactive power, and the current imbalance of a three-phase four-wire (3P4W) nonlinear load with generated renewable power injection into the grid simultaneously.

拉格朗日法实现多采样率的小数时延的实现，插值增加采样率，增加小数时延后，再以相同的速率抽取使其还原成原始采样率 (Lagrange method to realize the sampling rate of the realization of the fractional delay, interpolation increase the sampling rate, increase the decimal time delay, and at the same rate of extraction to make it back into the original sampling rate)

根据频率的不同，设置不同的滤波器，包括低通、高通、带通等(Depending on the frequency set different filters, including low pass, high pass, band pass, etc.)
