摘　　要：高精度轧制技术对冷轧机液压AGC系统的控制精度提出了更高的要求,本文对AGC系统中位置控制器、伺服放大器、位移传感器、压力传感器、控制调节器五个主要模型进行分析,对模型结构中测厚仪环节、延时器环节、死区环节、限幅器环节进行数学模型分析,分析了控制系统中各种因数对控制精度的影响并选择合理的控制策略,对冷轧机液压AGC系统的优化设计及系统控制性能的研究提供了基础。As the high-precision rolling technology has put forward a higher requirement for the control accuracy to the hydraulic AGC（ automatic gauge control）system of cold rolling mill, the models of position controller, servo amplifier, displacement sensor, pressure sensor and control regulator in AGC system are investigated, and the mathematic model analysis of gauge link, delay link, dead zone link, limiter link in the model strueture is performed. The influence of various factors in the control system on control accuracy is analyzed. The control strategy is selected reasonably. It is significant for designing the hydraulic AGC system of cold rolling mill and studying the response capacities of the system.
