μ-synthesis application to flexible structures: a review of the work of Balas

Advances in the control of flexible structures are necessitated by the stringent requirements on pointing and shape accuracy of some future space mission. The author reviews the work of Balas in the application of μ methods to an experimental structure. A discussion of μ methods is provided and the important area of uncertainty descriptions is covered. The μ-synthesis method has the advantage that it can take the structure of these uncertainties into account during design. The results of the μ-synthesis designs are discussed, and conclusions are given
