双电极气体保护焊系统的鲁棒自适应控制仿真

摘要

This paper establishes a multi-input and multi-output nonlinear model for the Double-Electrode Gas Metal Arc Welding.Based on gradient algorithm and pole assignment method,a robust adaptive controller is presented.The results of simulation show the robust adaptive controller is effective.%针对双电极气体保护金属极电弧焊系统,建立了一个双输入双输出的非线性模型,并基于梯度算法和极点配置自校正设计了鲁棒自适应控制器.仿真结果表明,该鲁棒自适应控制器具有良好的控制效果.
