摘要

To improve the robustness and performance of the dynamic response of a cage asynchronous motor

a direct torque control (DTC) based on sliding mode control (SMC) is adopted to replace traditional proportional-integral (PI) and hysteresis comparators. The combination of the proposed strategy with sinusoidal pulse width modulation (SPWM) applied to a three-level neutral point clamped (NPC) inverter brings many advantages such as a reduction in harmonics

and precise and rapid tracking of the references. Simulations are performed for a three-level inverter with SM-DTC

a two-level inverter with SM-DTC and the three-level inverter with PI-DTC-SPWM. The results show that the SM-DTC method achieves better performance in terms of reference tracking

while adoption of the three-level inverter topology can effectively reduce the ripples. Applying the SM-DTC to the three-level inverter presents the best solution for achieving efficient and robust control. In addition

the use of a sliding mode speed estimator eliminates the mechanical sensor and this increases the reliability of the system.
