An analytical modularized treatment of autopilots for guided projectile simulations

An innovative technique was developed by which piecewise analytical solutions to guidance and control transfer functions were obtained for use in larger but lower frequency computer simulations of guided munitions. Numerical integration, which is typically used to treat such transfer functions, significantly reduces the integration time step, and increases computer execution time for the overall simulation. The modularized analytical approach accommodates integration time steps associated with the lower frequencies of airframe dynamics which results in faster simulation execution and considerable savings in cost and execution time.
