| 中文摘要 |
| 针对级联无刷双馈电机, 提出了一种采用控制电机定子磁场定向的直接反馈控制方法. 首先推导出级联无刷双馈电机在控制电机定子磁场定向坐标系下的磁链方程和转矩方程. 然后将功率电机对控制电机的影响视为扰动, 在分析磁链方程和转矩方程的基础上得出磁链和转矩分别可由控制电机定子电流的直轴分量和交轴分量进行控制的结论. 该方法回避了求解复杂非线性方程的困难, 控制算法简单, 对电机参数的依赖性小. 仿真实验结果证
明了该方法的有效性. |
| 英文摘要 |
| For a cascaded brushless double-fed machine, we propose a stator-field-oriented direct-feedback control scheme. First, the flux equation and the torque equation in stator-field-oriented coordinates are derived, in which the influence from the power machine to the controlled machine is regarded as the disturbance. On the basis of the flux equation and the torque equation, we reach the conclusion that the flux and the total torque can be controlled respectively by the d-axis and q-axis currents of the controlled machine. This method avoids the complex nonlinear equation; it is simple and depends less on machine parameters. Simulation results validate this method. |
