基于FPGA的电机细分控制的研究

Study FPGA-based motor control subdivision

以前电机的细分控制技术借用硬件设备来实现对其细分,但是这个过程复杂成本较高,最重要的是在实现电机的细分过程还会出现电流震荡等现象导致细分不够精密。现在随着科技的不断进步,FPGA在当下很多电路中应用广泛,特别是对电机细分控制的应用上能起到很好的效果。文章以步进电机为研究对象简要探讨了步进电机细分驱动的基本原理,基于FPGA的硬件实现和仿真、测试结果分析,展示了步进电机细分的过程。

Previous subdivision control motor borrowed hardware technology to achieve its realization segments, but the process is complex higher costs, and ultimately there will be a shock at the realization of the motor current subdivision phenomena lead to insufficient segments precision. Now, with advances in technology, FPGA widely at present many circuit applications, especially prepared especially for motor control applications subdivision can play a very good effect, FPGA use the movement of the motor can be precisely controlled to achieve the motor precision positioning and positioning repeatability, solve a lot of practical problems in motor production, to bring a good performance.
