| Abstract: | 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. |
