| 摘 要： | 介绍了一种基于扩展卡尔曼滤波(EKF)的双Y移30°六相永磁同步电动机(PMSM)无速度传感器控制方法.本系统建立了六相双Y移30°绕组永磁同步电动机的数学模型和状态空间方程.通过选取dq旋转坐标系下的定子电流、电机转速和转子位置作为状态变量,选取定子电压和电流作为输入、输出向量,构建了EKF观测器.在dq旋转坐标下采用扩展卡尔曼滤波器获得转速和转子位置,并利用TMS320F2812型DSP芯片实现全数字控制.该方法不需要对多相永磁电机的结构作任何改变,同时适用于凸极和隐极永磁同步电机,在很宽的速度变化范围内都有较高的位置估计精度.实验表明该方法使系统具有更加良好的控制性能.
