Abstract :
An algorithm for finding improved D-scale transfer functions for robust control synthesis is presented. Generalized Popov multipliers and a linear matrix inequality (LMI) multiplier formulation are used to find D-scalings of polynomial order and arbitrary structure which provide advantages over the normal curve-fit scalings in a D-K iteration. The two primary benefits are enhanced convergence properties and the capability to handle repeated scalar block uncertainty. A flexible manipulator control example illustrates the advantages of the new D-scaling approach
