摘要 针对导弹电动伺服机构控制系统中无刷直流电机的三闭环控制需求,提出了一种DSP和FPGA组合设计电动伺服机构控制系统硬件设计方案,其中DSP实现复杂控制算法和实时控制程序,FPGA实现时序控制逻辑。同时还扩展了基于BU-61580总线协议芯片的1553B总线接口电路设计,以满足新型弹上总线式控制系统的接口要求。电机功率驱动电路采用智能功率模块(IPM)设计实现,位置、转速、电流信号检测分别采用绝对值编码器、旋转变压器和霍尔电流传感器设计完成。硬件调试结果表明,所设计的硬件电路工作稳定,达到了预期的设计要求。 A hardware design scheme of electric servo mechanism control system based on DSP and FPGA is proposed in this paper.Complex control algorithm and real-time control program were realized in DSP,and timing control logic is realized in FPGA.A 1553B bus interface circuit based on BU-61580 bus protocol chip is also extended to meet the interface requirements of new missile bus control system.The Motor power drive circuit is designed and implemented by intelligent power module(IPM).The position,speed and current signals are detected by absolute encoder,rotary transformer and Hall current sensor.Hardware debugging results show that the hardware circuit designed in this paper works stably and meets the expected design requirements.
