摘　　要：提出基于FPGA的多通道步进电机控制系统。首先,改进步进电机梯形加减速算法,降低其计算过程的复杂度;其次,对改进的算法在FPGA硬件平台上移植;最后,使用上位机的可视化操作界面与FPGA控制端共同搭建一套灵活的控制系统,使得参数可在上位机端实时更新配置。实验结果表明,该控制系统能够对电机启停频率进行精确控制,各阶段频率误差在2%以内,且不会出现失步与过冲现象。In the paper,a multi-channel stepper motor control system based on FPGA is proposed.Firstly,the stepper motor trapezoidal acceleration and deceleration algorithm are improved to reduce the complexity of its calculation process.Secondly,the improved algorithm is transplanted on FPGA hardware platform.Finally,the visual operation interface of the host computer and the FPGA control terminal are used.A set of flexible control system is built,so that the parameters can be updated in real time on the host computer.The final experiment results show that the control system can accurately control the start-stop frequency of the motor,the frequency error of each stage is within 2%,and the phenomenon of out-of-step and overshoot will not occur.
