摘　　要：为了满足直流电机伺服控制系统实时控制的要求,提高电机跟踪控制的精度,设计了基于单片FPGA的直流电机伺服控制系统.该控制系统采用Nios II内核实现位置环和速度环控制策略,系统的电流环通过并行硬件电路实现.为了减小电机的力矩波动,设计了基于Anti-Windup策略的PI速度控制器;为了减小系统的超调量和调节时间,位置环采用了超前滞后校正器.仿真和实验结果表明,设计的伺服控制系统具有较好的稳态精度和动态性能,满足系统的设计要求.In order to meet the real-time control requirement of servo system,a dc motor control system based on FPGA was designed.The position and speed controller were realized in the Nios II, and the current loop was executed in FPGA.In order to reduce the torque ripple,an Anti-Windup PI controller was designed.The lead-lag controller was adopted for the position controller.The simulation and experiment result showed that the servo control system had better steady and dynamic performance, which met the requirement of the servo control system.
