摘要
研究了用伪随机信号进行系统辨识的相关滤波原理 ,讨论了消除系统输出端稳态输出干扰、随机干扰及突变干扰的原理和逆重复伪随机信号参数的选择依据。在线辨识了某平整机液压自动厚控系统 (HAGC)的频响特性模型 。
Based on correlation filtering, the identification principle using random signals is investigated. The method can eliminate output steady disturbance, random disturbance and abrupt disturbance. Finally, a hydraulic AGC dynamic model of temper mill is identified by using reverse-repeat m sequences. The validation tests show that the method is practical and can be used for other engineering applications
