摘要
针对超低速运行的大口径望远镜,设计出一种基于单电源供电的TLV2374弧线永磁同步电机(PMSM)定子绕组电流采样电路,并将采样结果送给TMS320F2812的A/D口进行转换,采用数学的方法校正了其转换精度,经卡尔曼滤波后输出的电流满足高精度的大口径望远镜机架驱动的要求。
This paper designs one current sampling circuit based on TLV2374 to detect stator windings＇current of one arc permanent magnet synchronous motor（PMSM）, and the motor is applied for the large aperture telescope mount driving the low speed telescope.To convert the sampling current to digital signals,TMS320F2812 is used to complete the converter AID.The transformation results show that the sampling circuit can satisfy the large aperture telescope mount driving after the Kalman filtering.
