一个非常好用的国外牛人写的kalman滤波程序，(kfdemo.m is a Matlab script file to run a demonstration of the Bayesian Kalman filter. It loads file kfdemo.mat (saved as version 4 so that it will read in either v4 or v5 Matlab).The other files are called by kf.m (the Kalman filter) or included as they may be useful. Normalis.m normalises data to zero-mean, unit variance along components. I always do this before any further analysis.)

基于IP-IQ瞬时功率理论的APF仿真波形图，三相三线，如果需要还可以将三相四线传上来供大家学习交流。(Based on the IP-IQ instantaneous power theory of APF simulation waveform, phase three-wire, if necessary, can be three-phase four-wire pass up for the Learning Exchange.)
