Use of Entire Eigenstructure Assignment with High-Gain Error-Actuated Flight Control Systems.
Abstract
The theory of high-gain error-actuated feedback control, developed by Porter and Bradshaw, was applied to the design of various longitudinal decoupling flight control systems for an advanced aircraft. The controllers developed in this study utilized output feedback with proportional plus integral control to produce desirable closed-loop response with minimal interaction between outputs. This report describes how entire eigenstructure assignment can be used to determine appropriate measurement equations by assigning their corresponding transmission zeros. A singular value decomposition was used to choose the eigenvectors from their permissible subspaces. The results show that these modes appear in the output response, even for very high gain. Therefore, selection of good eigenvalues/eigenvectors was shown to be crucial to the successful application of this theory. This report also examined the effect of varying the other design parameters on the closed-loop system response.
