基于西门子S7 400控制器平台和TEMIC的交流变频调速装置,实现了1 450 mm单机架可逆冷轧机主传动的高性能控制。采用精确的计算方法,计算可逆冷轧机的调速转矩、加速转矩和空载转矩;使用速度设定平滑处理、负荷平衡和负荷观测器方法,进一步提高控制系统的稳定性。该传动控制系统投入后运行良好,速度控制精度和动态性能达到了较高标准。 Based on the Siemens S7 400 controller platform and the TEMIC AC frequency converter, a high-performance control of the main drive of the 1 450 mm single-stand reversing cold rolling mill was realized. Accurate calculation method is used to calculate the adjustable torque, accelerating torque and no-load torque of reversing cold rolling mill. Using the speed setting smoothing, load balancing and load observer methods, the stability of the control system is further improved. The transmission control system put into operation well, the speed control accuracy and dynamic performance reached a higher standard.
