摘要
基于系统输出信号过采样原理的系统反向辨识是一种新的盲辨识方法,这种方法不仅适用于最小相位系统,而且也适用于非最小相位系统。通过输出信号的过采样,可以获取未知输入信号和系统更多的信息。文中首先提出了这种解决盲辨识问题的算法,然后利用辨识出的系统模型恢复了源输入信号。这种方法在控制工程领域具有较高的实用价值。
Based on output oversampling of system inverse identification, is a new method of system identification, it can be applied in on not only minimum phase system but also nonminimum phase system. By oversampling on output signal, the information about unknown input signal and system can be gotten. This paper concern blind inverse problem arithmetic firstly, then restore the source signal by using system model which has been identified. This method has high practicality in control engineering field.
