Abstract: The problem of minimizing an integral quadratic functional on the trajectories of a linear singularly perturbed system with linear terminal constraints is considered. Asymptotic approximations are constructed in the form of a program and feedback to the optimal control in this problem. The main advantage of the proposed computational procedures is that, in their implementation, the original problem is decomposed into two unperturbed optimal control problems of lower dimension.

Key words: optimal control, linear system, quadratic functional, singular perturbations, asymptotic approximations, suboptimal synthesis.
