摘　　要：针对多数伺服系统控制器参数都是固化在控制器内部这一问题,以ARM7 LPC2478芯片和ALTERA EPM570T144为硬件平台,结合MFC框架编写可视化界面设计了PID参数可在线修改的直流伺服控制系统。详细介绍了系统的实现流程,包括CPLD程序设计、ARM程序设计和上位机程序设计。测试结果表明,系统能够快速响应控制命令,对PID参数的在线修改有利于提高系统的控制精度。For most servo system controller recently, the parameters were cured within the controller and it was difficult to change when the environment changed. A kind of DC servo system with PID parameter edited online was designed. Details about the implementation of the system include CPLD program design, ARM program design and host computer program design was given. The experimental results showed that the system was able to respond the control command quickly, and the modification of PID parameters online was helpful to improve the control precision.
