摘要：针对传统电压矢量控制时需要对相电流检测与坐标变换的问题，从简化控制算法、降低控制器成本出发，在对永磁同步电机原理和数学模型理解与分析的基础上，提出了一种基于d轴电压补偿的矢量控制方法。与传统矢量控制相比，该方法可有效避免控制算法的复杂性、保证控制系统的可靠性。根据实际需求，设计出以STM32为主控芯片的自动巡航电动车驱动器，实验测试和现场运行验证了该控制方法的可行性。

Abstract: Aiming at the problems of phase current detection and the coordinate transformation of the traditional voltage vector control, from the goal of lower controller cost and simplify the control algorithm,on the basis of understanding and analysis about the principle and mathematical model of permanent magnet synchronous motor,a vector control method based on daxis voltage compensation was proposed in this paper.Compared with the traditional vector control,this method avoided the complexity of the control algorithm and ensured the reliability of the control system effectively.Finally,according to the actual demand,STM32 as main control chip of automatic cruise vehicle (Automated Guided VehicleAGV) drive hardware circuit was designed,the experimental test and field operation showed that this control method was feasible.
