| 提出一种基于高阶滑模和加速度反馈的机械谐振抑制方法. 针对永磁同步电机定子电流和电机转速分别设计了高阶滑模控制器. 采用非奇异终端滑模面, 使得定子电流在有限时间收敛. 速度环引入加速度反馈, 降低机械谐振的影响. 仿真结果表明, 与PI 控制器分别结合陷波器以及加速度反馈的方法相比, 所提方法可以有效抑制机械谐振, 在保证动态响应性能的同时, 增强了系统对于负载扰动的鲁棒性. |
| 英文摘要 |
| Two higher-order sliding mode controllers are separately designed for controlling the stator current and the motor speed of a permanent-magnet synchronous motor. The nonsingular terminal sliding mode manifolds are utilized to make the stator current converge within a finite period of time. The acceleration feedback is introduced in the speed loop to reduce the influence of mechanical resonance. Simulation results show that, compared with the PI controller combined with a notch filter and the acceleration feedback, the proposed method suppresses mechanical resonance more effectively, ensures the desired dynamic response performance, and improves the robustness with respect to the load disturbance. |
