The discrepancy between the actual output voltage and expected output voltage of the matrix converter is calculated and added to the switch modulation matrix in the next sampling period as feedback.
该方法将实际输出电压和期望输出电压的比较偏差作为负反馈加到下一个采样周期的开关调制函数矩阵中。
ASM also provides an error correction formula deduced from matrix inversion theorem to clear up the error originated from approximate synchronous sampling.
近似同步法还提供了一个用基于系统辨识的矩阵反演定理导出的误差校正公式，它能消除近似同步采样造成的原始误差。
Finally, a choice of 1 out of N potential controlled mutual blocking logical circuits in the form of matrix and a potential controlled auto-sampling circuit have been recommended.
最后，本文提出了一种电位控制的矩阵式，N 中取1的互斥逻辑电路和电位控制的自动取样电路。
