Near optimal state feedback design for singularly perturbed systems by unified approach with an aircraft application

A state feedback design in two-time-scale systems is presented by a unified approach, which adopts /spl delta/ (delta) operators. The discrete system given is converted to a unified system and is decomposed into the slow and fast subsystems. Then, we formulate the necessary equations and algorithm to obtain the decoupled and exact solutions. Here, an aircraft implementation is made, and the results of both discrete and unified solutions are shown and compared.
