Abstract

A fifth-order discrete model is considered for an aircraft (longitudinal) control system which possesses three slow (velocity, pitch angle, and altitude) and two fast (angle of attack and pitch angular velocity) modes and exhibits a two-time scale property. Using recent results of the time scale analysis of discrete control systems, the high-order discrete model is decoupled into low-order slow and fast subsystems. The results of the decoupled system are found to be in excellent agreement with those of the original system. The two reduced-order subsystems require less computation for analysis and design.
