针对电液比例位置同步系统受到外部干扰,存在同步偏差问题,利用云模型理论设计了偏差补偿器对其进行修正。对位置偏差值进行云化处理后,依照云模型规则推理得到准确补偿信号,反馈给原系统作为同步偏差控制量。对预应力张拉设备的电液比例系统建立仿真模型,仿真分析表明,云模型偏差补偿器能够对出现的偏差自动调整,减小同步偏差,提高同步系统控制精度,系统的稳定性和鲁棒性也得到提高。
針對電液比例位置同步繫統受到外部榦擾,存在同步偏差問題,利用雲模型理論設計瞭偏差補償器對其進行脩正。對位置偏差值進行雲化處理後,依照雲模型規則推理得到準確補償信號,反饋給原繫統作為同步偏差控製量。對預應力張拉設備的電液比例繫統建立倣真模型,倣真分析錶明,雲模型偏差補償器能夠對齣現的偏差自動調整,減小同步偏差,提高同步繫統控製精度,繫統的穩定性和魯棒性也得到提高。

Aiming at the synchronous deviation problems of electro-hydraulic proportional position synchronous system while it is subjected to external disturbance , compensator is designed by theory of cloud model to correct it.The position deviation is processed by cloud, reasoning to get a accurate compensation signal by cloud model reasoning.And the signal is feedback to the original system as synchronous deviation controlled quantity.The simulation model of the electro-hydraulic proportional system of pre-stressed stretching equipment is established, the results show that the cloud deviation compensated controller could automatically adjust the deviation, reduce the synchronous deviation, and improve the control precision synchronization system.The stability and robustness of the system are also improved.
