Robust Flight Control System Design Using Utmost Compensator

Abstract

A New method is proposed to design a robust flight control system which is low-sensitve and robust stable.
The method is applied to design a control augumentation system (CAS) for the longitudinal flight control system of a typical small aircraft.
In an earlier paper the authors proposed a method to design a low-sensitive flight control system. The design method proposed here makes the closed-loop system robust stable against high frequency disturbances while being low-sensitive to certain class of the plant parameter variations.
In this paper, the class of plant parameter variation is examined from the flight dynamics. Then the robust flight control system design is performed to the above class of the plant parameter variation.
