摘要

实验建模是摸清物理现象本质的一种有效手段，而针对六自由度主被动一体隔振平台，它的实验建模是实现隔振的主动控制的前提，也是能否达到满意控制效果的关键。通过对物理空间到传感器坐标空间变换的推导，给出了传感器在布置上应该满足的条件。结合六自由度主被动一体隔振平台的先验理论知识，从测试所得信号出发，利用最小二乘估计的递推算法建立起了作动器到传感器的动力学模型，为隔振平台的振动主动控制打下了基础。

Abstract

Experiment modeling is an effective means to find out the essence of physical phenomenon. To 6-DOF active-passive vibration isolation platform, experiment modeling is the premise to make vibration isolation be active-controlled and also the key to gain satisfying control result. Conditions of sensors’ arrangement are presented by deriving the coordinate change from physical space to sensor space. Combining with the transcendental thesis of 6-DOF active-passive vibration isolation platform and the signal obtained from tests, the dynamic model of actuator-sensor is build up using least square estimation recurrence algorithm.
