Summary:In order to realize the vibration isolation performance of space micro-vibration active isolation platform, it is necessary to measure the vibration accurately. A kind of nine accelerometers allocation scheme containing redundant information is proposed and the corresponding formulae are presented. Then, with the method of using linear accelerometers to measure six degrees-of-freedom (DOF) acceleration, the Kalman filter algorithm is applied for the processing of the acceleration signal. Both simulation and experiment results show that the use of redundant information and Kalman filter can reduce noise and improve accuracy effectively.
