摘　　要：独轮自平衡代步车对轮毂电机的转矩控制性能要求较高,需要满足转矩响应速度快、转矩脉动小和噪音小等要求。轮毂电机常采用六步换相、两两导通的控制算法,控制性能不满足要求。本文提出了一种低速段采用离散空间矢量算法,高速段采用基于电机转速的磁场定向控制算法,较好地实现了转矩控制性能。试验结果表明,该算法能够获得更快的转矩响应速度和较小的转矩脉动,满足独轮车自平衡代步车的控制需求。The torque control of hub motor in self-balanced electric unicycle is required to get the higher performance than the six-step transformation direction method.In this paper,the discrete space vector in the low speed and field oriented control in high speed is proposed on the hub motor,which can achieve the better torque control.The experimental results show that this algorithm can accelerate torque corresponding speed,reduce torque ripple,and can meet the control requirements of the self-balanced electric unicycle.
