摘要：
The existing model predictive torque control (MPTC) for six-phase and three-phase permanent magnet synchronous motor (PMSM) series-connected system has some problems, such as heavy calculation burden and poor effect of zero-sequence current suppression. To solve these problems, a MPTC with predictive switching table was proposed in this paper. In order to improve the calculation efficiency of the core processor, a predictive switching table is constructed based on the basic principle of direct torque control. Only several basic voltage vectors are preselected to participate in the control of two PMSMs, reducing the alternative voltage vectors. In order to effectively suppress the zero-sequence current, a zero-sequence current suppression strategy was proposed. All the preselected basic voltage vectors were synthesized into virtual voltage vectors with zero-sequence voltage equal to given value, so that the optimal virtual voltage vector selected by the predictive algorithm could meet the control requirements of the system for zero-sequence current. Experimental results verify the feasibility and effectiveness of proposed control strategy. ©2022 Chin.Soc.for Elec.Eng.
