The positive real lemma provides the basis for constructing linear output feedback dynamic compensators for multi-input plants with independent amplitude saturations. Fixed-structure techniques are used to obtain full-and reduced-order feedback compensators along with a guaranteed domain of attraction. These results are then applied to the problem of rate… (More)
SUMMARY In this paper we synthesize linear and nonlinear output feedback dynamic compensators for plants with saturating actuators. Our approach is direct in the sense that it accounts for the saturation nonlinearity throughout the design procedure as distinct from traditional design techniques that first obtain a linear controller for the 'unsaturated'… (More)
In this paper, we present a new guaranteed cost bound motivated by the maximum entropy equation. This bound is of interest due to its sensitivity to skew-symmetric structured uncertainty, which is difficult to address by means of conventional guaranteed cost bounds.
— The implementation of a classic three dimensional PPN guidance against a high speed-nonmaneuvering target is analyzed. All the analysis is performed in a line of sight fixed coordinate. By utilizing an auxiliary function inspired from the tangential relative velocity at interception, a necessary and sufficient condition for the airfoil shape capture… (More)
