谐波分析是研究非正弦周期函数的重点之一,在数学理论上通过傅里叶变换可以求出周期函数的各次谐波,但是在工程实际中是很难获得非正弦周期函数的解析式,或者函数的解析式过于复杂不便于求积分,因此也就无法直接应用傅里叶变换。通过对畸变周期函数的波形进行等分采样获取数据序列,再以简短的三句指令对序列进行换算,获得畸变函数的各次谐波的幅值,结果证明了该方法能够简捷有效地进行非正弦周期函数的谐波分析。
This paper divides sampling data sequence based on periodic function waveform distortion,and then with a short three word instruction conversion on the sequence,the amplitude of each harmonic distortion function,obtain the validated.The re-sults proves that the harmonic analysis method proposed in this paper can be simple and effective for nonsinusoidal peri-odic function.
