| Abstract |
In this paper, the vector control and non-singular terminal sliding mode control (NTSMC) of interior permanent magnet synchronous motor (IPMSM) are proposed to improve the fast dynamic response and robustness. A proportional-integral (PI) control system is usually used as the speed controller of IPMSM since the simple structure. However, since a gain of PI controller is determined by the motor parameters, that have the nonlinearity, the speed control system of IPMSM cannot guaranteed robustness. Therefore, this paper proposes the speed control system using NTSMC and disturbance observer (DO) to improve the dynamic response and guarantee robustness of control system. Furthermore, the vector control algorithm is proposed considering the operating mode.
Considering the voltage drop, Newton-Raphson method is used for searching the current reference of optimal vector control. To verify the proposed control system, the simulation is implemented using MATLAB/Simulink. Finally, the effectiveness of the proposed control system is verified compared with the conventional control system. |
