摘　　要：基于冷轧卷取机张力控制系统的稳定性问题,指出动态张力模型是一个惯性环节,而且随着不同的工艺状况其模型参数也在变化,针对变参数模型,采用变参数的调节器才能维持张力系统动态响应特性不变.为此提出了基于确定性模型,并用数学方法计算出变化的参数,在工程最佳指标下去在线调节PI调节器参数,从而使控制系统在不同的工作条件下,维持工程最佳性能指标,达到最优控制效果.Based on the stability problem of the cold-rolled coiler tension control system, this paper points out that the dynamic tension model is a habitual link. If the parameters of the model is changing, varying parameters of the regulator is used to maintain the dynamic response characteristics of the same for tension of the system. Thus, based on the deterministic model, mathematical methods are used to calculate the changes in parameters, and according to the best indicators of project, the parameters of PI regulator are adjusted online to make the control system maintain the best performance indicators project in different conditions, and achieve optimal control results.
