digital fir filter with matlab2

This is the model of a single phase active power filter allowing the improvement of the electric power quality in the utility side

对adc采样信号进行频谱分析，计算信噪比，有效位数等等重要参数(Adc sampling signal for spectrum analysis, calculate SNR, the effective number of bits so the important parameters)

An extended Kalman filter (EKF) is employed to estimate the motor state variables by only using measurements of the stator fine voltages and currents. When applying the EKF, it was necessary to solve some specific problems related to the voltage and current waveforms of the BLDCM
