摘要
针对我校自主开发的新型虚拟轴三维坐标测量机构,进行了位置分析。在此基础上,设计并建立了以DSP为核心的虚拟轴三维坐标测量机构的步进电动机微机闭环控制系统,利用VC++6.0语言设计了系统的计算机控制软件。实验结果表明:由于系统采用的步进电动机体积小,转矩大,转速范围宽,因而简化了机械设计,减小了测量机构控制系统的体积,提高了系统的整体性能。其步进电动机闭环控制方案实现了虚拟轴三维坐标测量机构的高精度运动控制,为其实现高精度测量奠定了基础。
For a new type virtual coordinate measuring machine made in Jiangsu University,the position analysis is done,the closed -loop microcomputer control system of the stepping motor based on the DSP is designed and developed,the software of the microcomputer control system is written by VC＋＋6.0 language. The experimental results show that ,by using the stepping motors that are smaller in the volume ,bigger in the torque and wider in the range of speed than DC servo motor or AC servo motor,the mechanical design of the system is simplified ,the entire volume of the system is lowered. Furthermore ,the high-accuracy motion control of the measuring machine is implemented by the closed-loop control of the stepping motors. This provides a base for implementing the high- accuracy measure.
