| 针对带有负载力矩以及其他干扰的永磁同步电机（PMSM）调速系统，提出一种基于标幺化两相吸引律的PMSM有限时间速度控制方法。首先将被控转速误差标幺化以构造具有理想误差动态特性的两相吸引律；其次基于该两相吸引律设计速度控制器，同时设计有限时间扩张状态观测器估计系统中存在的未建模动态与外部干扰，实现了转速跟踪误差有限时间收敛；然后构造Lyapunov函数分析所提控制方法的稳定性；最后实验验证了所提方法的可行性。实验结果表明，所提方法能够实现快速、无超调的速度跟踪，具有良好的动、静态性能与抗干扰能力。 |

| A finite-time speed control method based on per-unit two-phase attraction law is proposed for permanent magnet synchronous motors （PMSM） suffering from load torque and other disturbances, etc. Firstly, the speed is transformed into the per-unit value to construct a per-unit two-phase attraction law with ideal error dynamic characteristic curve. Then, based on the two-phase attractive law, a speed controller is designed. At the same time, a finite time extend state observer is designed to estimate the unmodeled dynamics and external disturbances in the system, and finite time convergence of the speed tracking errors is realized. Secondly, Lyapunov function is constructed to analyze the stability of the proposed control method. Finally, the proposed method is verified in a PMSM drive platform. The experimental results show that the proposed method achieves fast speed tracking without overshoot, and demonstrate its good dynamic and steady-state performance and anti-disturbance ability. |
