This paper presents a unified approach to obtain simultaneously the continuous-time and discrete-time state space solutions for the composite state feedback control of singularly perturbed H systems. First, the scaled frequency domain realizations of dynamic systems are developed and then used to generate the unified H solutions that approach the H2 solution as the unified H norm design parameter is allowed to approach infinity. The realizations also account for the non-orthogonal cost function terms that occur in the unified singularly perturbed slow subsystem. Next, the unified H2 solutions are provided. Finally, the methodology is then applied to compute the reduced system, composite and full-order controllers gains for the dynamics of an F-8 aircraft model.
