摘　　要：多台多相电机串联驱动系统可以实现单台逆变器驱动多台电机的独立运行,与传统的多电机变速驱动系统相比有助于节省逆变器的数量和安装空间。多台多相电机串联驱动系统的转速调节多采用经典的PI控制,存在快速性与超调的矛盾,系统抗干扰能力比较弱。以对称六相和三相PMSM双电机串联系统为研究对象,将自抗扰控制(ADRC)应用到该串联系统的转速调节中,搭建起了基于ADRC速度调节器的对称六相和三相PMSM双电机串联驱动系统模型,通过仿真证明了自抗扰控制可以实现对转速的快速无超调跟踪,并提高系统的鲁棒性。The muhiphase multi-motor series-connected drive system can realize independent operation in which a single inverter drives several motors, and requires less quantity and installation space of inverters as compared with the traditional multi-motor variable speed drive system. Speed regulation of the muhiphase multi-motor series-connected drive system normally adopts classical PI control, there is contradiction between rapidity and overshooting, and the system anti-interference remains weak. In this paper, with the symmetrical six-phase and three-phase PMSM two-motor series-connected system as research objects, active disturbance rejection control （ADRC） is applied to the speed control of the series-connected system. A model of the symmetrical six-phase and three-phase PMSM two-motor series-connected system is established on the basis of the ADRC speed regulator. Simulation results verify that the ADRC Strategy can realize quick speed tracking without overshooting and improve the robustness of the system.
