摘　　要：针对AOD炉低速、重载、频繁启制动、强烈冲击作业负荷的特点,设计了带位置和转速PI调节器的双闭环控制系统。针对异步电机参数耦合强、非线性等特点,利用矢量控制对电机进行解耦。仿真实验表明,在8 s的调节时间内系统稳态和瞬态指标满足指标要求。For the features such as low-speed,overload,frequent startup-braking and strong impacting on loads in the AOD furnace,a double-closed loop control system with both the position PI regulator and speed PI regulator is designed.To solve the problems of strong coupling and nonlinear existed in the asynchronous motor,the vector control is used to decouple the parameters.The simulation results show both the static and dynamic position error can meet the technical needs.

关 键 词：矢量控制 前馈控制 位置控制
