| 中文摘要: |
| 为提高异步电机调速系统抗干扰能力，改善其动态特性，以异步电机矢量控制系统为基础，针对电流环和转速环分别设计了电流滑模控制器和转速滑模控制器，并利用指数趋近律来削弱抖振，详细阐述了控制器设计步骤。利用MATLAB／SIMULINK对滑模控制系统进行仿真，并与PI控制系统进行对比分析。最后利用dSPACE实时仿真系统对异步电机滑模变结构控制系统进行实验验证。结果表明，所设计的异步电机滑模变结构控制系统动态特性更好，抗干扰能力更强。 |

| In order to improve anti-disturbance capacity and dynamic performance of induction motor speed control system,this paper introduces current sliding mode controller and speed sliding mode controller with exponential reaching law based on vector control system.It contrasts simulation results of induction motor drive system based on sliding mode variable structure control(SMC) and PI control.At last,an experiment of induction motor sliding mode control system based on dSPACE is completed.It shows that induction motor sliding mode control system has better dynamic performance and stronger anti-disturbance capacity. |
