发布时间：2018-10-12 21:36
【摘要】：经过几十年的发展，步进电机已经应用于许多行业的自动化控制系统中。而步进电机的运行性能除与其本身性能之外，还和它使用的驱动器有着密切的关系，故对研究高性能的驱动器越来越受到人们的重视。当步进电机在低频工作时，由于其低频特性，使其分辨率不高，容易产生振荡，，运行不够平稳，无法满足高精密度的要求。而细分驱动是步进电机驱动技术中控制效果最好的，可以解决上述的问题。 在分析和整理国内外细分驱动技术文献资料基础上，本文利用电流矢量均匀旋转的SPWM正弦细分方法，设计了基于FPGA两相步进电机细分驱动系统。该系统由FPGA控制模块、FPGA核心板、电流保护电路、光耦隔离电路、功率放大电路和桥式驱动电路组成，并利用Quartus II软件对FPGA控制模块内部各模块进行了时序仿真，用示波器完成了对步进电机的细分电流观测。结果表明：系统硬件和软件设计合理可行，实现了对电机绕组电流细分的目的，步进电机的运行性能得到改善。
[Abstract]:After decades of development, stepper motors have been applied in many industries of automatic control systems. The performance of stepping motor is not only related to its own performance, but also closely related to the driver it uses, so people pay more and more attention to the research of high performance driver. When the stepping motor works at low frequency, because of its low frequency characteristic, its resolution is not high, it is easy to produce oscillation, and its running is not stable enough, which can not meet the requirement of high precision. The subdivision drive is the best control in the step motor driving technology, which can solve the above problems. Based on the analysis and arrangement of domestic and foreign literature on subdivision drive technology, a two-phase stepping motor subdivision drive system based on FPGA is designed by using the SPWM sinusoidal subdivision method with uniform current vector rotation. The system is composed of FPGA control module, FPGA core board, current protection circuit, optocoupler isolation circuit, power amplifier circuit and bridge drive circuit. The timing simulation of each module in FPGA control module is carried out by Quartus II software. The subdivision current of step motor is observed by oscilloscope. The results show that the hardware and software design of the system is reasonable and feasible. The purpose of subdividing the winding current of the motor is realized, and the performance of the stepping motor is improved.
