DDSRF-PLL
本文论述了在控制的一个重要方面电网连接的电源转换器,即检测基波正序分量的电网电压不平衡和扭曲的条件下。明确地,提出了一种积极的基于一种新的序列检测器双同步坐标系的解耦锁相环(双dq–PLL),完全消除了检测误差传统的同步参考框架(SRF–锁相环PLL)。(This paper deals with an important aspect in the control of grid connected power converters, that is, detecting the fundamental positive sequence components of the grid under unbalanced and distorted voltage conditions. Clearly, a positive decoupling PLL a new sequence detector based on dual synchronous coordinate system (double DQ - PLL), the complete elimination of the traditional synchronous reference frame detection error (SRF - PLL PLL).)

竞争性自适应重加权算法(CARS)是通过自适应重加权采样(ARS)技术选择出PLS模型中回归系数绝对值大的波长点,去掉权重小的波长点,利用交互验证选出RMSECV指最低的子集,可有效寻出最优变量组合。(The competitive adaptive weight weighting algorithm (CARS) uses adaptive heavy weighted sampling (ARS) to select the wavelength points with large absolute value of the regression coefficient in PLS model, remove the wavelengths with small weight, and use interactive verification to select the lowest subset of RMSECV, which can effectively find the optimal combination of variables.)
