Investigation of a Third Order Baro-Damped Vertical Channel of INS.

Abstract

The optimization of the three gains of a third-order baro-inertial vertical channel has been formulated as a stochastic optimal control problem, with the objective of minimizing the mean squared altitude error due to the noise induced altitude error and a disturbance of known magnitude. For a vehicle carrying out a TERCOM-update immediately following a vertical descent, and being subjected to a disturbance input to the vertical channel, optimum gains are presented and the performance is analyzed through a simulated flight in a Monte Carlo analysis. Performance comparisons between the optimized gains and the classical gains are also presented. The results show a significant performance improvement over the classical gains for a vehicle carrying out the TERCOM-update. (Author)
