TL;DR: In this article, conditions for complete separation of slow and fast regulator designs are formulated and a second order approximation of the optimal performance is achieved without the knowledge of the small singular perturbation parameter.
Abstract: For systems with slow and fast subsystems a near-optimum state regulator is composed of two subsystem regulators. Conditions for complete separation of slow and fast regulator designs are formulated. A second order approximation of the optimal performance is achieved without the Knowledge of the small singular perturbation parameter.

Journal ArticleDOI
TL;DR: In this paper, a matrix norm condition is given under which the large eigenvalues of a two-time scale system will be sufficiently separated from the small eigen values, and a feedback control design is proposed in which two gain matrices are used for separate placement of small and large values.
