摘要

Synthesis of optimal H controllers is formulated as a loop-shaping problem where the desired closed-loop shape to be pursued is a uniform frequency response of the largest singular value. The weighted H2 optimization technique used in the linear quadratic Gaussian design with loop transfer recovery is exploited in the loop-shaping procedures to generate a sequence of H2 controllers converging to the optimal H2, controller. The resulting optimal H controller not only has the inherent robust property due to H criterion but also possesses the nice H control structure, being easy to compute and implement. A fighter example and a large space structure example are demonstrated to show that the numerical accuracy of the present H2-based H synthesis is comparable to the conventional H approach, i.e., γ-iteration, but with reduced computational efforts.
