Abstract

An approach is presented that develops an accurate model of parametric uncertainty suitable for structural control design and analysis. This approach requires a number of different data sets to capture the dynamics of the system and its variability. Using an identification technique, the modal parameters of the finite element model are estimated. The parameter estimates are combined into a parametric uncertainty model in the form of mean errors and bounds on the modal parameters, which can then be used for robust control design and analysis. The development and utilization of this uncertainty model is demonstrated using the middeck active control experiment, a shuttle middeck experiment that flew on STS-67 in March 1995
