| 摘 要： | 文以永磁同步电机为对象，采用矢量控制方案，首先我们研究了基于PI的控制算法，在仿真基础上指出了PI算法存在的一些不足。在此基础上我们研究了基于扩张状态观测器（ESO）前馈补偿和线性比例反馈控制的永磁同步电机速度环控制算法，仿真实验表明，这种方法可以提高系统的动态性能和抗扰动能力。

Research of Permanent Magnet Synchronous Synchronous Speed-Adjusting System on field Vector Control |

| Abstract: | Taking PMSM as the controlled plant, this paper studies the control system based on vector control, first, the servo control scheme based on PI control law is studied. Some limitations of PI based control scheme are pointed out. Then we study a speed control algorithm for PMSM consisting of feedforward compensation based on extended state observer and linear proportional feedback control. The simulation results indicate that this algorithm can improve the dynamics and disturbance rejection properties of the PMSM speed-adjusting system. |
