Based on the real work process of coiler at worksite , an electro - hydraulic servo system including the inner position - adjusting loop and the exterior pressure - adjusting loop is developed in order that unit roller can evite the step automatically 本研究参考实际现场卷取工艺，研制了压力调节为内环、位置调节为外环的双闭环电液伺服控制系统，以实现助卷辊对台阶的自动回避。
