compensation-of-dead-time
交流伺服系统中的死区效应分析与补偿分析了逆变器的死区效应产生的原因及其对交流伺服系统控制性能产生的影响,指出死区补偿的关键
在于电流相位的获取,为了克服实际系统中电流零点的模糊性,提出了一种基于两相静止坐标系下的前馈死
区补偿方法. 该方法通过对三相输出电流一个周期内补偿电压进行傅里叶变换,发现仅需补偿1 ,5 ,7 次谐波
分量即可消除死区效应. 仿真和试验结果验证了这种方法的正确性和可行性.(AC servo system analysis and compensation of dead time effect of the inverter dead time effect causes the impact of the control performance of the AC servo 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.)

papr_windowing
reduction to papr in ofdm with Peak Windowing:
The basic idea of peak windowing is to multiply the envelope of OFDM
signal with a weighting function . Therefore,
~xE (t)= xE (t) f (t)
where
XE(t) =[x(t)]
The weighting function given by:
f (t)= 1-Σ α .w(t- t )
t-t
w(t) : is the window function.
t : denotes the position of a local maximum of the envelop xE(t) .
α : attenuation constant .
When the amplitude of envelop amplitude of the OFDM signal exceeds a threshold, a window function is applied to the envelop of the OFDM signal to eliminate the peak amplitude. windowing results in a smooth signal.
Hanning window function will be used for w(t)
As a matter of fact , other windows such as cosine, hamming and Kaiser may be employed.
