Abstract

Weight shapes and locations are investigated for H₂, H_∞, and the general mixed H2/H infinity optimization methodologies. The design model is normal acceleration command following for the F-16 (SISO) at Mach 0.6 and Sea Level, which yields a nonminimum phase and unstable plant. H₂ design types include LQG, LQG/Sensitivity, and LQG/Tracking. Robustness and tracking are the objectives of the central H infinity process. Both H_∞ optimal and suboptimal controllers are examined, with the suboptimal controller shown as the practical choice for this plant. The mixed H₂/H_∞ setup allows the tradeoff between H₂ tracking and noise rejection, and H_∞ robustness. Results of weight choices on all designs are discussed, with the mixed H₂/H_∞ design being favored.
