It offers fast dynamic response, lower total harmonic distortion (THD), and, in many cases, constant switching frequency.

Sliding Mode Direct Torque Control (SM-DTC) of an induction motor enhances traditional DTC by replacing hysteresis controllers with sliding mode controllers (SMC) to reduce torque/flux ripples and increase robustness against parameter variations. It offers fast dynamic response, lower total harmonic distortion (THD), and, in many cases, constant switching frequency.

Key Features and Improvements:
  • Reduced Ripples: Unlike conventional DTC, which uses hysteresis comparators resulting in high torque/flux ripple, SM-DTC uses a smooth sliding surface to reduce these ripples.
  • Robustness: SMC provides strong, reliable control even under varying motor parameters and load disturbances.
  • Reduced Switching Frequency Variations: The approach helps to stabilize the inverter switching frequency, decreasing acoustic noise.
  • Methodology: It involves designing two distinct sliding surfaces for flux and torque control, using Lyapunov stability theory to design the control signals.
  • Implementation: Often simulated using MATLAB-Simulink to confirm enhanced transient performance and lower overshoot compared to classic DTC.

In this paper, an alternative method is presented for induction motor drive known by the model Predictive Torque Control (PTC). This technique includes the inverter model in control design and does not use any modulation block. The optimal selection of inverter switching states minimizes the error between references and the predicted values of control variables by the optimization of a cost function. Consequently, it reduces ripples and solve DTC drawbacks. A fuzzy logic controller replaces the traditional PI controller to ensure more accurate speed tracking and increase the robustness against disturbance and uncertainties.

The DTC-SVM system is applied to a low-power three phase induction motor. The tests considering the operations under speed reversion are conducted by means of computational simulations in the MATLAB software together with the Simulink environment.
