本文以本钢引进的美195—B、鞍钢引进的美280—B电铲为实例(195—B与280—B电铲除斗容大小与电机容量有差异外其电气控制系统完全相同,本文为叙述和推导方便,确定以280—B电铲为分析对象),建立矿用挖掘机提升系统的动态模型,并实现了微型计算机仿真,最后在综合分析280—B电铲PID调节器校正前后的动态指标的基础上,提出了调节器参数的优化。
In this paper, the United States imported by Benxi 195-B, Anshan Iron and the introduction of the United States 280-B shovel as an example (195-B and 280-B electric shovel bucket bucket size and electrical capacity difference is the same except outside the electrical control system, this article Describe and derive conveniently, determine the 280-B electric shovel as the analysis object), build a dynamic model of mining excavator to enhance the system, and achieve the micro-computer simulation. Finally, after a comprehensive analysis of the 280-B shovel PID regulator calibration Based on the dynamic index, the optimization of the regulator parameters is proposed.
