Minimax Optimization for a System of Line-of-Sight Stabilization

Abstract

The minimax problem of stabilization is solved for a line of sight near a programmed trajectory. The motion of this line is described by a system of fourth-order linear differential equations. In this problem, the perturbations are considered as the deviations of the initial position from zero and as time-varying perturbations. The stabilization is performed by a linear feedback. The feedback coefficients are obtained as optimal for the worst possible perturbations.
