摘要
在电机控制中,为了达到较好的控制效果,需要对转子的位置信号进行角度细分,以实现对转子位置进行精确的定位。在介绍锁相环倍频电路实现角度细分的同时,提出了用软件实现角度细分的新方法,并以开关磁阻电机为控制对象,分别用这两种方法进行了实验,结果表明,在控制精度和可靠性上,软件方法要优于硬件方法。软件角度细分法在算法方面还有待优化,以进一步提高控制精度。
In order to gain a more effective control of the motor, an angular fine division for the posi- tional signal of the rotor is needed to fix a precise position for the rotor. This paper introduces new method of realizing angular fine division by software, simultaneously introducing PLL （ phase - locked loop） multiple frequency circuit to realize angular fine division. The two methods are used respectively by taking SRM（ switched relucance motor） as control object. The experimental results indicate that the software method is better than the hardware one in control precision and reliability. The sofeware method of angu- lar fine division needs to be optimized to improve the control precision.
