摘要
针对龙门移动式镗铣床双龙门框架移动的不同步问题,采用迭代学习算法抑制单轴直线电机控制系统中存在的扰动。同时,采用基于模糊理论的同步控制方案,将模糊控制器应用在双电动机驱动的轴间反馈回路,抑制不同步引起的不平衡扭矩。仿真结果表明,此种控制策略有快速的响应能力和对干扰的抑制能力,有很高的同步精度,能保证系统的同步运行。
According to the asynchrochronism of double granty frames in gantry- moving type boring - milling machine tool, an Iteration Learning Algorithm （ILC）was proposed to suppress periodic disturb- ance in the system. Also a synchronization scheme based on fuzzy theory was proposed in this paper. To limit the torque that caused by the asynchronization, the fuzzy controller was designed and placed in feedback circle of axes driven by dual servo motors. The simulation results show that the proposed scheme has rapid response and disturbance suppression, which can guarantee the synchronous operation of the system.
