摘　　要：应用Spartan-3E系列的FPGA实现了对步进电机可变细分控制．采用自底向上的模块设计方法，综合运用了电流跟踪型SPWM、PI调节、闭环控制、EDA等技术，有效地解决了步距角的高细分问题．实验结果表明：高细分大大提高了步进电机的控制精确度，降低了电机运行噪声，消除了低频振荡．The design, using FPGA of Spartan-3 E series, has realized a subdivision-varlation control system for stepping motor. Employing the bottom-top design method, this scheme integrates the current-feedback SPWM principle, the PI regulating technique, the closed-loop control as well as EDA design technology. The problem of high-subdivision stepping angle is solved effectively. Experimental results indicate that the control system can improve the control precision of stepper motor and make it run more smoothly.
