| 摘要: |
| 针对永磁同步电机滑模控制中系统的全局渐进稳定性，设计了基于非线性滑模面的非奇异终端滑模速度环控制器，保证了系统有限时间的收敛，同时避免了系统的奇异问题，减小了系统的抖振，提高了系统的稳态精度。为了提高系统的抗干扰能力和控制精度，设计了扰动观测器，并将观测扰动值反馈到速度控制器中。针对位置传感器安全性、可靠性等问题，设计了滑模位置观测器，实现了位置信号的实时快速精确跟踪。仿真结果表明，提出的控制策略能够有效地提高系统的控制精度与响应速度，增强了系统的抗干扰能力。 |

| Abstract: |
| In order to enhance the global asymptotic stability of the system in sliding mode control for permanent magnet synchronous motor (PMSM), a nonsingular terminal sliding mode speed loop controller based on nonlinear sliding mode surface is designed in this paper, which ensures the finite-time convergence and improves the steady state precision of the system. Meanwhile, it avoids the singularity problem and reduces the chattering problem of the system. In order to improve the anti-interference ability and control precision of the system, a new disturbance observer is designed, which feeds the observed values back to the speed controller. Aiming at the safety and reliability of the position sensor, a sliding mode position observer is also designed which enable the real-time, fast and accurate tracking of the position signal to be realized. The simulation results show that the control strategy proposed in this paper can effectively improve the control precision and response speed of the system, and enhance the anti-interference ability of the PMSM control system. |
