Novel SVPWM Update Strategy to Solve Calculation Delay in PMSM Driver

PWM output delay caused by calculation is widely presented in permanent magnet synchronous motor drive systems, which reduces control performance, accuracy, and stability. This article proposes a novel enhanced SVPWM update strategy, which is easy to implement and achieves completely delay-free output. Compared to traditional methods, this approach is simpler to compute, does not rely on motor parameters, and does not require an increase in sampling frequency. The effectiveness and superiority of the proposed algorithm are verified through comparative experiments.
