FLIGHT CONTROL APPLICATION OF NEW STABILITY ROBUSTNESS BOUNDS FOR LINEAR UNCERTAIN SYSTEMS

This paper addresses the issue of obtaining bounds on the real parameter perturbations of a linear state-space model for robust stability. Based on Kronecker algebra, new, easily computable sufficient bounds are derived that are much less conservative than the existing bounds since the technique is meant for only real parameter perturbations (in contrast to specializing complex variation case to real parameter case). The proposed theory is illustrated with application to several flight control examples.
