Abstract:

For the ever popular linearization via feedback flight control technique, order reducing conditions are discussed according to the singular perturbance theory, singular regions of the outer loop decoupling matrix for various command modes are determined; tracking errors of commonly used control formats are analyzed; three controls deflection command apportioning strategies are proposed when the controls are redundant. Numerical simulations on the post stall turn and other maneuvers verify the analysis results.

Key words: linearization via feedback, singular perturbance, decoupling matrix, tracking errors, redundant controls
