摘要
针对逆变弧焊电源系统参数时变和外界干扰的特点,就逆变弧焊电源的燃弧状态模型,基于模型跟踪技术指标,选择加权函数,设计了最优H∞鲁棒控制器,该控制器不仅有较好的抗干扰能力,而且对参数时变有较强的抑制作用。仿真结果表明了设计方法的有效性。
Burning arc state model was proposed for time-varying and exterior disturbance of arc welding inverter power source system. Based on model tracking target, the weighting function was selected, and optimal H∞ robust controller was derived. The controller has better resistance to disturbance,morever it can effectively curb time-varying. Finally, a simulation was given to illustrate the validity.
