摘要
讨论了用Ｖｏｌｔｅｒｒａ级数表示的高阶频域响应函数与非线性系统的描述函数之间的关系，利用Ｖｏｌｔｅｒｒａ级数推导并定义了一种新的描述函数即广义描述函数，对广义描述函数进行了一定的讨论和研究。
A relationship between the higher-order frequency response function of the Volterra series model and the well-known describing function representation for non-linear systems is derived.By using Volterra series,a new class of describing function,the generalized describing functions is derived and defined.
