Model Predictive Torque Control for a Dual Three-phase PMSM Using Modified Dual Virtual Vector Modulation Method

Single voltage vectors applied in the conventional model predictive torque control (MPTC) for multiphase motors do not only suffer from serious and stator flux ripples but also cause large harmonic current. To address aforementioned challenges, an MPTC using a modified dual virtual vector modulation method is proposed to improve operational performance of three-phase permanent magnet synchronous motor. Virtual are synthesized as candidate set restrain A transformation introduced consider both duty cycle modulation. The simultaneously reduced by addressing limitations nonuniform units. Furthermore, null then inserted expand range steady-state performance. Moreover, sawtooth carrier adopted challenge asymmetric switch sequence caused Finally, experimental results presented verify effectiveness superiority method.
