| 摘要: |
| 针对表贴式永磁同步电机(permanent magnet synchronous motor, PMSM)转速环存在的负载扰动、参数失配等不确定性问题，提出一种基于新型趋近律的抗扰滑模控制策略。首先，提出一种新型自适应趋近律，所提趋近律在等速项中引入系统滑模变量的自适应增益，解决了传统指数趋近律收敛速度与滑模抖振的矛盾问题，减小了跟踪误差，且避免了趋近速度突变问题。然后，基于所提新型趋近律和非奇异积分终端滑模面设计了转速环滑模控制器。最后，为进一步提高系统的抗扰性能，设计扩展滑模扰动观测器观测并补偿转速环的不确定性扰动。仿真与实验结果表明，所提抗扰滑模控制策略能有效提高电机调速系统的动态性能和鲁棒性。 |

| Abstract: |
| To address uncertainties in the speed loop of surface-mounted permanent magnet synchronous motors (PMSMs), such as load disturbances and parameter mismatches, an anti-disturbance sliding mode control strategy based on a novel reaching law is proposed. First, a new adaptive reaching law is formulated, in which an adaptive gain of the system sliding variables is introduced into the constant-speed term. This design resolves the traditional conflict between convergence speed and chattering in exponential reaching laws, reduces tracking errors, and avoids abrupt changes in reaching speed. Subsequently, a speed-loop sliding mode controller is designed by integrating the proposed reaching law with a nonsingular integral terminal sliding surface. To further enhance disturbance-rejection capability, an extended sliding mode disturbance observer is implemented finally to estimate and compensate for speed-loop uncertainties. Simulation and experimental results indicate that the proposed anti-disturbance sliding mode control strategy significantly improves the dynamic response and robustness of the motor speed control system. |
