本文介绍了热、冷连轧机AGC系统的仿真模型结构及其在各种不同条件下的计算结果,对前馈补偿加入的方式,采样控制周期、测量滞回误差、机械间隙、张力调节死区的设置等提出了相应的分析意见。已建立的仿真模型可以在工程上直接应用于研究、设计、分析相应的系统。 This paper introduces the simulation model structure of AGC system of hot and cold tandem rolling mill and its calculation results under different conditions. The methods of adding feedforward compensation, sampling control cycle, measuring hysteresis error, mechanical gap, tension adjusting dead zone The settings such as the proposed analysis of the corresponding views. The established simulation model can be directly applied in engineering research, design, analysis of the corresponding system.
