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.
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.
