为了抑制高速线材连轧机直流调速系统未知外扰（负载力矩）对系统造成的不利影响，设计了离散负载扰动观测器及带前馈扰动补偿的直流调速系统，并将重构的负载扰动应用于微张力控制．现场实验表明，所设计的系统有效地改善了调速系统的动、静态性能，改善了微张力控制效果，提高了线材质量．
In order to suppress the adverse influence of unknown disturbance (load moment) on the system caused by DC motor speed control system of high-speed wire rod rolling mill, a discrete load disturbance observer and a DC speed regulation system with feedforward disturbance compensation are designed. The reconstructed load disturbance Applied to micro tension control. Field experiments show that the designed system can effectively improve the dynamic and static performance of the speed governing system, improve the effect of micro tension control and improve the quality of wire rod.
