摘　　要：为解决空间光学次镜的高精度定位需求设计了一种六自由度并联次镜平台,对并联平台进行运动学分析,并设计了平台的闭环控制系统。根据设计的并联次镜平台结构,搭建了实验硬件系统,编写了软件控制程序,对运动分析结果及控制系统进行实验验证。实验结果表明,所设计的控制系统可以实现六自由度并联次镜平台的运动控制,运动控制精度能够达到0.02mm。In order to meet the high-precision positioning requirements of the space optical assembly second mirror technology, a six-degree of freedom(6 DOF) parallel mechanism of Second Mirror Platform is designed, the kinematic analysis of the platform is presented, and the loop-locked control system of the platform is designed. According to the design of the 6 DOF platform and the control system, the experimental system is conduct. The experimental result indicates that the designed control system can meet the requirements of the motion control and the precision can approach to 0.02 mm.
