多维微驱动器纳米定位系统的研究

SUBMICRO-POSITIONING SYSTEM BASED ON MULTI-DIMENSIONALULTRAPRECISE MICRO ACTUATORS

  • 摘要: 本文论述了在有多维微驱动器定位系统中,应用PID和FU ZZY联合控制的方式解决定位中存在的速度调节与系统振荡的矛盾;应用坐标变换方式解决多维定位系统中的干涉现象;以及在实际系统中,采用直线电机与微驱动器联合驱动的硬件构架,并配以上述控制策略,对定位系统进行粗定位和微定位,最终实现大范围和高精度的定位系统.

     

    Abstract: In this paper, an approach is presented to resolve confliction between speed adjustment and system oscillation in a submicro-positioning by using PID and FUZZY controlling method. A coordinate transformation is applied to minimization the inter-axial interference in the multi-dimensional submicro-actuator positioning system. In the experiment, the composition for the control system is made of three linear motors and three submicro-actuators, with is capable of realizing the positioning of a wide range and submicro precision.
