Self Adjusting Digital Controller for Aircraft Systems.(Dept.E)

Abstract

The paper describes an algorithm for designing self adjusting optimal controller for digital aircraft control systems to cope with the variation of the aircraft parameters under different flight conditions. The aircraft parameters which depend on the flight condition are continuously measured. A deadband zone around each of the parameters of a presetting flight condition is initiated. Any deviation from these bands will individually perturb the controller reference for obtaining sensitivity functions. These sensitivity functions will be used to adjust the feedback parameters of the aircraft control system. The proposed technique is suitable for implementation on real world control systems. The design of the proposed control represents an extension for that concepts included in [1].
