The design of near-optimal observer-based controllers for discrete two-time- scale systems with inaccessible states is considered. The controller is established by the design of the controllers of slow and fast subsystems via the quasi-steady-state method. The stability bound of the singular perturbation parameter and the value of the minimum performance index for the actual closed-loop system are determined. A digital flight control system of a twin-engine aircraft is used to demonstrate the desired scheme.
