    摘要(Abstract):

    對于YK7232A磨床液壓伺服控制系統由較多的分立元件構成,可靠性較低,響應速度較慢,而且故障率較高,不便于系統維護等問題.采用了EDA設計技術,將系統中大部分的分立元件以及PID控制模塊,采用邏輯重構的方式集成到體積較小的FPGA芯片中,形成具有低功耗、高集成度的液壓伺服片上系統.采用Verilog-HDL語言對伺服控制系統的大部分模塊進行邏輯重構.著重介紹了濾波整形模塊以及增量式浮點數PID控制模塊的設計,經Modelsim仿真校驗達到了設計的要求.并最終設計出液壓伺服控制片上系統頂層原理圖.
    The hydraulic servo control system of YK7232 A Grinder is composed of quite a few discrete components, with lower reliability, slower response speed, and higher failure rate, which is not convenient for system maintenance. This paper uses EDA design technology to integrate most of the discrete components and PID control modules in the system into a smaller FPGA chip by using logic reconfiguration to form a hydraulic servo system-on-chip with low power consumption and high integration. It uses Verilog-HDL language to restructure most modules of the servo control system. The design of the filter shaping module and the incremental floating-point PID control module are introduced in detail. The simulation requirements of Modelsim have been met. Finally, the top-level schematic diagram of the hydraulic servo control system-on-chip is designed.
