The analytic model and dynamic response solution for torsional vibration of main driving system on rou-gher of rolling mill were studied.
分析了粗轧机主传动扭振模型及动态特性计算方法。
In order to solve the problem,the main drive system of rolling mill control problem was transformed into a standard H_∞ design problem by constructing a expanded controlled plant for the parameters time-varying,load disturbance and the DC motor that has the nonlinearity uncertaint.
为克服该缺陷,针对具有参数摄动、负载扰动和电枢反应引起的非线性不确定性的直流驱动轧机主传动系统控制问题,基于H∞理论设计了轧机主传动系统的鲁棒状态反馈控制器,并利用两自由度控制方法设计了主传动系统的前馈补偿控制器。
Because the main drive system of Hot-rolling mill receives 105 - 106 times impulsive torques every year, which happen when the billet steel comes into rolling mill, the fatigue design load of the main drive system should be determined by the load spectrum of the peak value of impulsive torques.
热轧机主传动系统咬钢时受到强大的冲击扭矩作用,每年的冲击次数达105-106,因此应以咬钢时的冲击扭矩峰值载荷谱作为主传动系统的疲劳设计负荷。
