| 摘 要： | 为提高框架系统控制性能,采用系统扫频方法对系统实际模型进行扫频辨识。由于加工和安装工艺等原因,框架不同位置处的摩擦力矩差异较大。研究了固定补偿值摩擦力矩补偿算法和变补偿值积分摩擦力矩补偿算法,并重新进行了扫频。根据辨识得到的模型设计了校正网络,提高了系统控制性能。

| Abstract: | In order to improve the control performance of frame control system, control system frequency-sweeping method is used to identify the system model. Due to the machining technology and installation process, there is large frictional moment difference between different positions of the frame. The friction moment compensation algorithm of fixed compensating value and variable compensating value integration are studied, and frequency sweeping is conducted. Then the identified system model is used to design the corrective network, and the control performance of frame system is improved. |
