Analysis and Implementation of Optimal Estimation and Control for the FJSRL Seismic Isolation Platform.

摘要

The study is directed toward the analysis and implementation of an optimal estimator (Kalman filter) and an optimal regulator to provide active control of the inertial instrument test platform. The design specifications are to maintain angular position within + or - .001 arcseconds and angular rate with + or - .00001667 arcseconds/second. A forced separation concept is utilized to allow the independent evaluation of the Kalman filter and the optimal regulator. Optimal and suboptimal Kalman filter models are developed and evaluated at physically realizable sampling rates. A general optimal estimation and control algorithm is developed and a proposed sequence of algorithm computations is presented. (Author)
