摘　　要：在加工大型、重型零件时,由于重型龙门机床多电机驱动系统具备复杂性和同步性,导致了其控制精度下降。为了解决上述问题,提出基于模糊PID算法的重型龙门机床多电机驱动控制方法。构建详尽的重型龙门机床多电机驱动模型,精准刻画系统动态特性及多电机间复杂力学作用。在此基础上设计基于模糊逻辑的PID控制器,通过智能调节PID参数,提高系统对参数变化和外部干扰的适应性,以此制定多电机同步控制策略,结合主从控制模式、模糊神经PID控制器及实时状态监测反馈,实现多电机高精度同步控制。实验结果表明,研究方法能够显著提高机床的控制精度,有效应对负载变化和扰动影响,为高精度机床加工提供有效的解决方案。When machining large and heavy parts,the complexity and synchronization of the multi-motor drive system of heavy gantry machine tools lead to a decrease in their control accuracy.In order to solve the above problems,a multi-motor drive control method for heavy gantry machine tools based on fuzzy PID algorithm is proposed.A detailed multi-motor drive model of heavy gantry machine tool is constructed to accurately portray the dynamic characteristics of the system and the complex mechanical interaction between the multi-motors.On this basis,a fuzzy logic-based PID controller is designed to improve the adaptability of the system to parameter changes and external disturbances by intelligently adjusting the PID parameters,so as to formulate a multi-motor synchronous control strategy,which combines the master-slave control mode,fuzzy neurological PID controller,and real-time state monitoring and feedback,to realize the multi-motor high-precision synchronous control.The experimental results show that the research method can significantly improve the control accuracy of the machine tool,effectively respond to load changes and disturbance effects,and provide an effective solution for high-precision machine tool processing.
