摘　　要：焊接装置以C8051F020单片机为核心控制芯片,通过对数字直流伺服系统、PI控制器和驱动接口设计以及对电流、电压传感器、角度传感器的反馈信息的检测与处理,实现了对电机的控制,完成了各种焊接要求.焊接速度的平稳恒定是焊接质量的保障,利用单片机对PWM波脉宽的调制和增量式PI控制器对电机转速的调节,实验表明,该方法可以实现焊接速度的精确控制.C8051F020SCM as the core control chip of welding equipment has realized the control of the motor and completed all kinds of welding requirements through digitized servo system, PI controller and drive interface. It has also examined and processed the feedback information of circuit sensor, voltage sen- sor, angular transducer. The stable and invariable nature of welding speed is an insurance of welding quali- ty. SCM is used to adapt PWM pulse width and the incremental PI controller is used to adapt the rolling speed of the motor. Experiments have shown that this method has achieved the precise control of welding speed.
