| 摘 要： | 文章以一三平动自由度并联机构为研究对象，有效解决了因理论模型控制实际机构引起的空间层面不对称的问题，进而提高了系统的控制精度。首先建立了坐标系和分析误差源，在此基础上借助空间矢量链分析方法，推导了含误差参数机构控制的正、逆解模型，有效地解决了因立柱导轨垂直度误差引起的机构误差问题。仿真结果验证了模型的正确性，研究成果已应用此类机构的开发中。

| Abstract: | Based on the theory of a class of 3-DOF parallel kinematic machines and using vector analytical method, this paper presents the forward and inverse control model with 18 error parameters. Computer simulation is proposed, and its result shows that the position control model with 18 parameters is able to solve successfully the machine error problem produced by the vertical error of guid eway, promote the control accuracy of machine and satisfy system control requirement. The research product is applied to this kind of machine. |
