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.
