摘要 焊枪摆动系统的速度平稳性是焊接质量的重要保障。针对摆动系统低速运行特点,为了解决静摩擦和库伦摩擦给伺服系统带来的稳态误差和低速爬行问题,依据仿真通过增大比例增益来减轻低速爬行现象,提出了变参数的PI控制方案。经过对伺服电机实际测量得到低速爬行的速度范围,通过固定参数与变参数控制器速度响应对比,证实了增大比例增益能够减轻低速爬行问题,提高伺服控制系统运动性能。 The speed stability of the oscillation system is an important guarantee for the quality of welding. Based on the low-speed running characteristics, the static friction and the Coulombic friction will lead to the steady-state error and the low-speed crawling problems to the servo system. To solve these problems, multi-PI parameters control method is proposed, in which the low-speed range is devided into 64 groups, and different Kp ,Ki parameters are designed for every speed after measurment and analysis. It is proved that this method can meet the accuracy need of the oscillation speed.
