摘要
对具有高阶传递函数的某控制系统仪器 ,采用延长序列的傅立叶变换方法 ,准确、快速地得到了其动态频率特性 ,并用改进的Levy方法准确辨识出了系统模型。
Describes the dynamic frequency measurement of control system equipment based on extended sequence Fourier transform method, which has higher order transfer function. The frequency parameters of the system are gained rapidly and correctly. Moreover, its mathematical model is accurately identified by modified Levy method.
