| 摘 要： | 在Ｐｒｏｎｙ算法的基础上，结合互相关函数计算，提出了一种适合于多个有不同时延的振荡于波组成的复杂振荡波形的模型参数估计方法──互相关Ｐｒｏｎｙ算法。仿真波形的分析及高压断路器操作振动实测加速度信号的分析都表明这个方法能获得满意的结果。

| Abstract: | This paper presents a combined algorithm-Correlation Prony algorithm for modelling the parameters of complex singnals with decayed oscillating waveform which contains a series of suboscillations with different frequencies and time delay. The algorithm has proved to be satisfactory in parameters modelling for two cases: for simulated composed signal analysis and for detection of acceleration signals of operating vibrations in high voltage circuit breaker testing. |
