| 摘 要： | 永磁同步曳引机是典型的非线性多变量强耦合系统,在同步旋转坐标系下dq轴电流存在耦合,传统的PI控制器无法实现解耦,提出一种基于内模控制原理和空间矢量算法相结合的高性能永磁同步曳引机解耦控制方法,用内模控制策略控制理想电机模型,对定子电流交叉耦合电势动态解耦,提高系统的动态响应性能,同时在整个电流闭环过程中对参数摄动和外扰动具有良好的鲁棒性,这种方法不需要额外的电机参数和检测硬件,试验结果验证了这种方法有效可行。

| Abstract: | The permanent magnet synchronous traction machine was a typical nonlinear multivariable coupled system, there was crosscoupling between dqcurrents in synchronousframe, the dqcurrents could not be decoupled by the traditional PI, a combination of high performance permanent magnet synchronous traction machine control method based on the intima of the control principle and space vector algorithm decoupling was proposed, the internal model control (IMC) was used to control an ideal motor decoupled model, which was designed to dynamic decoupling of the stator current crosscoupling potential, the system dynamic response performance was improved,the robustness of parameter uncertainties and disturbances in the current loops was satisfied, extra motor parameters and hardwares were not necessary in this method, the experimental results showed the feasibility and effectiveness. |
