1、上海交通大学硕士学位论文基于DSP的排爆机器人控制系统的设计与实现姓名:杨惠华申请学位级别:硕士专业:机械电子工程指导教师:杨汝清20060201上海交通大学硕士学位论文摘要的可靠性,文章还提出了在软件上增加抗干扰性的方法——设置软件陷阱和设置看门狗模块。本文针对具有较大关节齿轮间隙的机械手,采用了数字PID的控制方法,达到了机械手三关节联动的控制效果。为了解决关节具有较大齿隙的缺陷,在程序中设置了死区控制,并且适当的调低速度,尽量避开了齿隙环节对控制系统的影响。同时,本文还提出了以相位超前校正网
2、络来补偿齿隙环节的方法,并且在matlab中验证了方法的正确性。本文还简单介绍了优化DSP控制程序的方法。经过优化后的控制程序可以运行在更高的采样率基础上,增加了系统控制的稳定性。最后,本文介绍了行走模块,机械手联动和无线通信模块等的功能调试。实践证明,DSP作为排爆机器人的控制器是完全可行的。关键词:排爆机器人,数字PID,数字信号处理(DSP)芯片,无线通信,齿隙环节上海交通大学硕士学位论文摘要DESIGNANDREALIZATIONOFCONTROLSYSTEMOFEXPLOSIVEORDA
