| 摘要:根据纸机传动系统中存在的负荷分配易失衡等特点,分析了单分部间多电机拖动同一负载时传动点间耦合关系的特性,基于交流异步电机空间矢量控制的数学模型,提出了刚性耦合负荷分配采用总线通信转矩控制，以及柔性耦合负荷分配采用总线通信转速控制的控制策略；再利用MATLAB/SIMULINK软件对这两种控制策略进行建模与仿真,最终验证了两种控制策略的可行性与实用性。 |
| Abstract:According to the characteristics of easy to be imbalance of the load distribution in paper machine drive system, the features of the coupling relations between the multipoint drive in the single division when multi-motor controls the same load were analyzed. Based on mathematical model of SVPWM control technique, control strategies i.e. bus communication torque control was used for rigid coupling in load distribution and bus communication rotating speed control was used for flexible coupling in load distribution were proposed. The simulation modeling to these two control strategies was established by MATLAB/SIMULINK, the feasibility and practicability of these two control strategies were validated. |
