摘　　要：针对自平衡两轮车平稳行驶需提供高精度电机转子位置信号的问题,提出并实现基于线性霍耳传感器的永磁同步电机控制系统。采用设计的零漂抑制电路,消除位置信号的零点漂移;通过DSP分区间读取位置传感器信号,解决运算溢出问题,提高了位置信号解算精度。实验结果表明:该方法能有效抑制线性霍耳位置零漂,保证永磁同步电机位置检测精度要求,实现自平衡两轮车平稳控制。To achieve smooth driving of the two-wheeled self-balancing vehicle which requires highly precise motor rotor position signal, a permanent magnet synchronous motor （PMSM） control system based on linear hall-effect sensors was developed. A drift suppression circuit was designed to eliminate the zero drift of position signals; processing the position signals with different methods according to different ranges using digital signal processor （DSP） solved arithmetic overflow and improved the accuracy of the position signal. Experimental results illustrate the proposed method can effectively eliminate zero drift of linear hall-effect sensors which ensure PMSM position detection accuracy and achieve smooth control of two-wheeled self-balancing vehicle.
