中文摘要：
提出一种基于高阶终端滑模的永磁同步电机转速控制方法，提高了系统的鲁棒性和响应速度．根据矢量控制原理，设计了非奇异终端滑模面，使得电机转速、直轴电流、交轴电流在有限时间内达到给定值．同时，采用高阶滑模消除抖振，保证系统的稳定性．仿真结果表明，和PI控制方法相比，电机转速能够更快地跟踪给定值，并且，系统对于负载扰动具有较强的鲁棒性．
英文摘要：
A permanent magnet synchronous motor speed control based on high-order terminal sliding mode is proposed to improve the robustness and the response speed of the system. Based on the vector control principle, nonsingular terminal sliding modes are designed to make the motor speed, the d-axis current and the q-axis current reach the given values in a finite period of time. Meanwhile, high-order sliding modes are utilized to eliminate the chattering phenomenon, and to guarantee the stability of the system. The simulation results show that the motor speed can reach the given value more rapidly than that of a proportional integral（PI） control; and the system is robust with respect to the load disturbances.
