Optimized pulse patterns, such as the selective harmonic elimination pulse width modulation (PWM) pattern (SHE-PWM) are used to suppress current harmonics at steady-state. However, achieving fast dynamic performance is very difficult in systems operated by SHE-PWM. This paper proposes a method that combines the performance of SHE-PWM at a steady-state with the fast torque response of model predictive direct torque control at the transient-state. Finally, the control performance of the proposed system is evaluated based on the experimental results.
