摘要

In this paper, synthesis of optimal H controllers is formulated as a loop-shaping problem where the desired closed-loop shape to be pursued is a flat frequency response of the largest singular value. Weighted H2 optimization technique used in LQG/LTR is exploited in the loop shaping procedures to generate a sequence of H2 controllers converging to the optimal H controller. The resulting optimal H controller not only has the inherent robust property due to H criterion but also possesses the nice H2 control structure, being easy to compute and implement. A flight control example is demonstrated to show that the numerical accuracy of the present LQG-based H synthesis is comparable to the conventional H approach, i.e., γ-iteration.
