【摘 要】The number of AC motors in the large asphalt mixing station is up
to a few dozen. In order to improve the accuracy of the proportion of raw
materials,the uniformity of vibration and stir,the coordination-synchronous
problem is to be considered in the multi-motors control. And large power
motors are easy to appear saturated during the long time load operation.
Aiming at this phenomenon,the ant-windup control strategy was designed
to improve the control performance of the system,and the correctness of
the strategy was verified by simulation. The monitoring system of the
mixing station was designed with PLC+Delphi,and the control flow of the
mixing station was simulated. The system could be used to monitor the
current of multi-motors in real time,and the communication protocols
