摘　　要：无差拍控制(DBC)是一种应用于整流器电流内环的预测控制,但该算法对系统参数敏感,当采样受到持续噪声干扰时波形畸变严重。为此,此处提出了一种基于DBC的白噪声抑制算法,实验结果表明,该算法在较大电感参数偏差下能保持稳定,在白噪声干扰下能够显著降低电流畸变率。Dead-beat control(DBC)is a predictive control applied to the current inner loop of rectifier,but this algorithm is sensitive to system parameters and causes severe waveform distortion when sampling is subjected to continuous noise interference.Therefore,a white noise suppression algorithm based on DBC is proposed.The experimental results show that the algorithm can maintain stability under large inductance parameter deviations and significantly reduce current distortion rate under white noise interference.
