The key to the effect of active power filter compensation is compensating current :in order to make it better tracking instruction current,using the RBF neural network of hysteresis controllers,with a "K-means, RLS" algorithm for training is applied.Simulation results show that, neural network control is effective for fast variables, clould improve the performance of hysteresis control,...
Abstract-On the basis of traditional PI control for DC-side voltage of Active Power Filter(APF), a parameter self-adjusting fuzzy PI control method is designed in this paper. In order to adjust the parameter itself, it is can be used fuzzy control rules to control the fuzzy output variables according to fuzzy input variables. The simulation results show that the method has smaller overshoot, faster...
Two methods for detecting harmonics and reactive currents: p-q theory and ip-iq theory, which are based on three-phase instantaneous reactive power theory, are presented. The model of shunt active power filter(APF), based on the two methods in MATLAB, is built. In the model, the root-mean-square (RMS) part takes place of the low pass filter (LPF) part. But the two methods can't work properly when...
