The two - order volterra model can be identified with the correlation analysis and frequency - domain analysis when the input is gaussian white noise 通过相关分析、频域分析，采用高斯白噪声输入信号，可以对二阶volterra模型进行辨识。

This approach only requires the noise inputs to be energy - bounded instead of gauss white noises . the main results can be expressed by lmi after some matrix manipulations 该方法不需要限定系统的噪声输入信号为高斯白噪声，而只要求噪声信号为能量有界。
