基于信号处理中的自适应噪声抵消技术，提出了一种神经元自适应谐波电流检测方法，该神经元有两个相位正交的正弦输入，其权值用基于ｄｅｌｔａ规则的改进学习方法来调节。所提出的方法适用于有源电力滤波器的谐波电流检测。仿真结果表明了该方法的有效性。
Based on the adaptive noise cancellation technique in signal processing, a novel adaptive harmonic current detection method based on delta-sigma is proposed. The neuron has two sinusoidal inputs whose phases are orthogonal. adjust. The proposed method is suitable for harmonic current detection of active power filter. Simulation results show the effectiveness of the method.
