| 摘 要： | 将永磁同步电机(PMSM)作为石油钻机系统的驱动设备时,针对快速响应和强鲁棒性的控制要求以及复杂工况下的外部扰动问题,提出了基于前馈补偿的石油钻机系统PMSM预测控制策略。在该方法中,对电机转速环采用以电机数学模型为基础的预测控制,以实现PMSM的快速响应和提高鲁棒性,并引入扩展状态观测器进行扰动前馈补偿。仿真结果表明:与电机转速PI控制和动态矩阵控制相比,该控制策略响应速度更快,超调量小,在负载干扰下转速波动小且能更快地恢复至稳定值。

| Abstract: | When the permanent magnet synchronous motor (PMSM) was used as the driving device of the oil drilling rig system, the predictive control strategy of the PMSM in the oil drilling rig system based on feedforward compensation was proposed in view of the control requirements of fast response and strong robustness and the external disturbance in complex conditions. In this method, the predictive control based on the motor mathematical model was applied to the motor speed loop to realize the fast response and improve the robustness of the PMSM, and the extended state observer was introduced to realize the disturbance feedforward compensation. The simulation results showed that, compared with the speed PI control and dynamic matrix control of PMSM, the new control method had faster response and less overshoot, and the speed under the load interference exhibited less fluctuation and could be more quickly restored to the stable value. |
