摘要
针对门式起重机在运行中出现的两电机不协调问题进行了理论分析 ,采取变频调速 ,PLC和上位机相结合的最优控制方案 ,使双电机达到自动同步 。
This paper makes a theoretical analysis about the non coordination problem in the running of the two electrical machinery of the door model crane, adopts the best control scheme of the combination of speed governor of frequency conversion, PLC and superordinate computer , makes both electrical machineries to coordinate automatically and gives the results of the computer simulation.
