| 摘 要： | 因脉冲熔化极气体保护焊(Pulse gas metal arc welding,GMAW-P)焊接电弧负载非线性与时变性的特点,GMAW-P焊接电源-电弧系统的研究、设计及其控制参数的选定有其固有的难点。采用基于Matlab/Simulink扩展工具S函数模块设计技术,建立GMAW-P焊接电源-电弧系统动态仿真模型。基于所建立的仿真模型,在完成对控制器参数优化设计的同时,实现对GMAW-P电源-电弧系统的抗弧长干扰仿真研究。试验证明,仿真计算结果和试验结果具有较好的一致性,验证了所建仿真模型的正确性、控制系统调节器优化参数的适应性及电源控制系统的动态性能,为GMAW-P焊接电源-电弧系统仿真建模研究及控制器参数的优化设计提供了新的途径。
