摘　　要：由于冷带轧机操作侧与传动侧位置子系统的内部参数不确定性与不一致性,液压两侧位置系统的动态性能不同,这往往导致轧机生产的板材厚度不一致.文章基于全驱系统方法提出了一种参数自适应同步控制策略.首先,建立了液压位置系统的辨识模型与全驱模型;然后,基于辨识模型采用递推最小二乘算法对子系统的未知参数进行辨识;进而,针对建立的全驱同步系统模型,设计了参数化控制器,从而达到闭环系统稳定,以及两侧子系统的同步.最后,仿真结果表明了同步控制方案的有效性.Due to the uncertainty and inconsistency of internal parameters of posi-tion subsystems on the operation side and transmission side of the cold strip rolling mill,the dynamic performance of the hydraulic position system may differ,which of-ten leads to inconsistent thickness of the produced sheets.In this paper,a parameter adaptive synchronous control strategy based on the fully actuated system method is proposed.First,an identification model and a fully actuated system of the hydraulic position system are established.Then,the unknown parameters of the subsystems are identified by using the recursive least squares algorithm based on the identification model.Subsequently,a parameterized controller is designed for the established fully actuated synchronous system model to achieve the stability of the closed-loop system and the synchronization of the two subsystems.Finally,a simulation result demonstrates the effectiveness of the proposed synchronous control scheme.
