摘　　要：摘要：为了满足特殊领域对伺服系统的应用要求，提高步进电机的定位精度设计一种多路输出伺服控制电路。以单片机和FPGA作为核心控制芯片、控制全桥驱动电路，通过采样电阻和高精度运算放大器获得步进电机的相电流，从而得到步进电机的电流细分控制。并给出步进电机控制电路和实际控制效果。The positioning precision of stepper motor is improved and a multi-channel output servo control circuit is designed to meet the application requirements for servo system in the special field. The whole bridge driving circuit is controlled by using single chip microcomputer and FPGA as the core control chip. The phase current of the stepping motor is obtained through the sampling of electric resistance and high precision amplifier so as to re- alize the subdivision control of the stepper. And step motor control circuit and actual effect are given.
