On the robustness of MEOP design versus asymptotic LQG synthesis

An analysis is presented of generalized LQG (linear-quadratic Gaussian)-type algorithms with regard to robustness characteristics. Comparisons are made of the maximum entropy/optimal projection (MEOP) methodology versus the linear quadratic Gaussian with loop transfer recovery (LQG/LTR) technique and the parametric robust linear quadratic Gaussian synthesis procedure. The performance of a reduced-order direct controller design is compared with the full-order designs on a example representative of typical flexible-structure dynamics.<
