摘要
针对描述函数的局限性,通过一个实例,由原描述函数为Ne=4πA,推导了考虑至3倍基波频率的一种新的计算描述函数Ne=4πA(2-43sin2ωt)的方法.仿真结果表明,同原描述函数的分析结果相比,该新算法在适用范围内,可更好的与仿真结果一致.
Considering the inadequacy of the describing function, through an example Ne=4πA, this paper presents a new method of calculating the descriptive functions, in the case of the frequency of 3w. Simulation experiments show that Ne=4πA(2-43sin2ω t), in comparison with the conclusion by normal descriptive function, the results of the new algorithm within a proper range are satisfactory.
