| 摘要: |
| 为了满足激光焦点控制系统的位置和速度响应要求，设计了一种轴向放置、轴向磁化的环形永磁体自复位的3自由度激光焦点磁力驱动微动平台。根据该微动平台的结构进行力学分析并建立动力学方程，在此基础上进行微动平台的比例、积分、微分控制实验和鲁棒控制实验。通过两种不同控制策略的对比分析，结果表明，两种控制策略都能实现微动平台的稳定驱动，但是在比例、积分、微分控制策略下，响应速度更好，在鲁棒控制策略下，抗干扰能力更好。 |

| Abstract: |
| In order to satisfy the requirements of position and velocity response of the laser focus control system, a three-degree-of-freedom laser focus magnetically driven micro-motion platform was designed. According to the structure of the freestyle platform, the mechanical analysis and the establishment of the kinetic equation were carried out. On this basis, the PID(proportion integration differentiation) control experiment and the robust control experiment of the fretting platform were carried out. Results show that the two control strategies can achieve a stable driving of the micro motion platform. However, under the PID control strategy, the response speed is better; while under the robust control strategy, the anti-jamming ability is better. |
