Abstract:

A computer program was used to assess the relative performance of different measuring devices employed in a system subject to random errors. The system was composed of the simulation of a vehicle entering the atmosphere of the earth, a measuring scheme to gather data about the state variables, a data processor from which the best estimate of the state variable was obtained from the measurement data, and a control scheme which used the processed data in order to calculate the proper control force. A statistical evaluation of the performance of the system was obtained by using as a measure of the performance the terminal quadratic dispersion matrix which is the terminal mean square deviation of the state variables away from a nominal value. Various measurement schemes were compared by comparing the resulting terminal dispersion matrices of the system. The terminal dispersion matrix was calculated by two different methods in the program by Monte Carlo analysis and by the application of linear theory.
