【摘要】 针对课题的要求,提出了一种利用混合式码盘测量永磁同步机(PM SM)磁极位置的解决方案,在硬件投入较少,几乎没有增加软件负担的情况下对PM SM实现磁极位置的快速、准确测量,实验证明该方案是切实可行的。在实验基础上还给出了软硬件的设计方案,并就实施方案过程中出现的问题进行了细致的分析。更多还原

【Abstract】 With the requirement of the theme,we have put forward a method of using the mixed optical encoder to measure the position of magnetic polar of the permanent magnet synchronous motor(PMSM).The experiments have proved that it is possible to give a fast and accurate measurement to the magnetic polar of PMSM under the circumstances that with less hardware and no any software additional burden.We also have proposed new designing schemes for hardware and software,and careful analyze to the problems which emerged during the implementation.更多还原
