摘　　要：大型沥青拌和站中交流电机的数量达几十台,为提高各原料的配比精确性、振动和搅拌的均匀性,在控制中需要考虑到多个电机协调同步问题,且大功率电机长时间负载运行,易出现饱和。针对这一现象,设计抗饱和控制策略来提高系统的控制性能,并通过仿真验证了策略的正确性。采用PLC+Delphi设计了拌和站的监控系统,模拟了拌和站生产的控制流程,该系统可实时监测到多个电机的电流,设计了模块之间的组合通讯协议,试验结果表明,此方法能够提高产品质量指标。The number of AC motors in the large asphalt mixing station is up to a few dozen. In order to improvethe accuracy of the proportion of raw materials,the uniformity of vibration and stir,the coordination-synchronousproblem is to be considered in the multi-motors control. And large power motors are easy to appear saturated during thelong time load operation. Aiming at this phenomenon,the ant-windup control strategy was designed to improve thecontrol performance of the system,and the correctness of the strategy was verified by simulation. The monitoring systemof the mixing station was designed with PLC + Delphi,and the control flow of the mixing station was simulated. Thesystem could be used to monitor the current of multi-motors in real time,and the communication protocols between themodules were designed. The test results show that the method can improve product quality index.
