High precision measurements in various applications rely on active seismic isolation to decouple the experiment from seismic motion; therefore, closed feed-back control techniques such as sensor blending and sensor correction are commonly implemented. This paper reviews the active isolation techniques of the Albert Einstein Institute seismic attenuation system (AEI-SAS). Two approaches to improve the well known techniques are presented. First, the influence of the sensor basis for the signal-to-noise ratio in the chosen coordinate system is calculated and second, a procedural optimization of blending filters to minimize the optical table velocity is performed. Active isolation techniques are adapted to the mechanical properties and the available sensors and actuators of the AEI-SAS. The performance of the final isolation is presented and limitations to the isolation are analyzed in comparison to a noise model. The optical table motion reaches approximately ##IMG##

AEI 10 m原型设备的AEI-SAS的本地主动隔离

在各种应用中的高精度测量都依赖于主动隔震来使实验与地震运动脱钩。因此，通常采用封闭式反馈控制技术，例如传感器混合和传感器校正。本文回顾了阿尔伯特·爱因斯坦研究所地震衰减系统（AEI-SAS）的有源隔离技术。提出了两种改进众所周知的技术的方法。首先，计算传感器基础对所选坐标系中信噪比的影响，其次，对混合滤镜进行程序优化，以最小化光学平台速度。主动隔离技术适用于机械性能以及AEI-SAS的可用传感器和执行器。介绍了最终隔离的性能，并与噪声模型进行了比较，分析了隔离的局限性。光学平台运动达到大约## IMG ##
