摘　　要：通过对内蒙古某炼钢厂连铸机动态轻压下液压压下系统的研究,根据现代控制理论,在分析连铸机工作特性的基础上,建立了电液位置伺服系统的状态空间模型,设计了系统的二次型最优控制。仿真结果表明,系统具有良好的动态品质和跟踪性能。The dynamic soft reduction hydraulic system of continuous caster of a steel mill in Inner Mongolia was studied. According to modern control theory, the working characteristics of continuous caster were analyzed, the state-space model of electro-hydraulic position servo system was established, the quadratic optimal control of the system was designed. Simulation results show that the system has good dynamic quality and tracking performance.
