摘要
介绍一种用于高速永磁同步电动机控制的转子位置检测方法,该方法采用旋转变压器/数字转换器AU6802N1,将旋转变压器输出的模拟信号转化为数字位置信号。设计了AU6802N1与旋转变压器和TMS320F2812之间的接口电路,并提出了一种具有较强容错性的位置信号数字处理方法。试验表明,该方案能够准确地实现电机位置和速度的检测。
A method of rotor position detection in the high speed permanent magnet synchronous motor (PMSM) control system was presented ,which transformsed analog signals of resolver to digital signals using the resolver digital converter AU6802N1. The interface circuit for them was designed. Also the interface circuit between AU6802N1 and TMS320F2812 controller was described in detail. At last,methods of sampling and processing position signals was introduced. Experiment result showed that interface circuit's performance was steady and can exactly measure the speed and position of the PMSM.
