A program was written to simulate the three axis attitude control system of LES-89. The underlying theory to the computer simulation and detailed outlines of each of the subroutines involved in the complete program are described. Whenever feasible, the simulation was written to duplicate as closely as possible the logic and signal flow of the actual digital attitude control system. Each subroutine was thoroughly verified as accurate by independent and integral system operation, as well as by theoretical estimates, analog computer simulations and actual experimental data. A substantial compilation of data from this working program was catalogued and analyzed for attitude control system evaluation and optimization. This program also proved itself to be invaluable in the analysis of stability and performance of the complete attitude control system.
