采用边界元方法求解电磁响应及系统本征模问题(boundary element method to investigate the eigmode and green function of the EM )

compensation of dead time effect of the inverter dead time effect causes the impact of the control performance of the INVERTER system, and pointed out that the dead time compensation, the key lies in the current phase of the acquisition, in order to overcome the practical zero of the current ambiguity of the system is proposed based on the two-phase stationary coordinate system under the feedforward dead-time compensation method. by the offset voltage of the three-phase output current cycle Fourier transform is found only compensation 1, 5, 7 harmonic components to eliminate the dead time effect. simulation and experimental results verify the correctness and feasibility of this approach.

it s knn simulation by matlab toolbox

说明：  行向量绘图，在matlab中对于含有大量的数据，单独在一张静态的图上是显示效果是很不理想的，这个程序实现了在matlab中以示波器的形式动态的显示器波形图(Row vector graphics in matlab in containing a large amount of data, alone in a static chart is to show the effect is not ideal, the realization of this procedure in matlab in the form of oscilloscope waveform display dynamic)

说明：  OFDM仿真程序，信道估计采用LS,MMSE,LMMSE,DCT等方法，做了个比较，ofdm那个是主程序(OFDM simulation program, channel estimation using LS, MMSE, LMMSE, DCT and other methods, made a comparison, OFDM that is the main program)
