摘　　要：针对传统矢量控制响应速度慢、抗扰性能差等问题,在考虑6相电动机空间矢量解耦特点的基础上,提出了一种基于反推算法的6相感应电动机新型矢量控制方案.首先,构建了6相感应电动机数学模型,并通过合成新虚拟电压平衡矢量来确定空间电压矢量脉宽调制方案;其次,应用反推原理设计了反推控制器取代传统的PI控制器,实现电动机对给定信号的跟踪控制,保证整个系统具有全局稳定性;最后,在MATLAB/Simulink中进行系统的仿真验证.将仿真与PI控制方法进行了对比.结果表明,该方案具有响应速度快、控制精度高、抗扰能力强和改善定子电流波形等优点,而系统设计的有效性得到了验证.To solve the slow response and poor robustness in traditional vector control（VC）, considering the characteristics of space vector decoupling of sixphase motor, a novel VC of sixphase induction motor was proposed based on backstepping control algorithm. The mathematical model of motors was established, and the new virtual voltage balance vector was used to determine the space voltage vector pulse width modulation. The backstepping principle was adopted to design the backstepping controller for replacing the traditional PI controller, and the tracking of the induction motor for the given signals was realized to guarantee the global stability of system. The system was verified by the simulation in MATLAB/Simulink, and the simulation result was compared with that of PID control method. The results show that the strategy has the advantages of rapid response, high control precision and strong antiinterference ability with improved stator current waveform, and the efficiency of system design is proved.
