| 摘 要： | 根据小波变换的多分辨率分析特性，设计的2分频分解／综合滤波器，将油田联合站降脱水系统的输入输出信号进行分频处理，根据分频处理后得到的信号，估计出沉降脱水系统各频带内传递函数低阶副近模型的参数，然后利用综合滤波器，将各频带的逼近模型进行组合，最终得到联合站沉降脱水系统的传递函数模型，仿真结果验证了该模型的正确性。

| Abstract: | A two_frequency_division decomposition/synthesis filter is designed from the multi_resolution analystic characteristics of wavelet transformation for frequency division treatment of signals to and from the multi_purpose dehydration system.The parameters of low_order approaching models for the transfer functions within different frequency bands of the dehydration system are estimated from the signals obtained through the frequency division treatment,and the approaching models for different frequency bands are then combined using the synthesis filter to obtain the transfer function model of the multi_purpose dehydration system.The correctness of this model is verified by simulation results. |
