Sliding mode approach applied to sensorless direct torque control of cage asynchronous motor via multi-level inverter

open access: yesProtection and Control of Modern Power Systems, 2020
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
