Abstract : This research was concerned with the robust optimal control of systems subjected to structured uncertainty. The design objective was to minimize the induced system norm (i.e. maximum gain) in the cases of l2/L2 and l(inf)/L(inf) inputs. Major results were obtained in the case of linear discrete-time systems with nonlinear/time-varying uncertainty and for continuous systems controlled by digital computers (sampled-data systems). The sampled-data results are now a part of the MATLAB u-tools toolbox and the structured uncertainty results for discrete-time systems has led to an efficient 'D-K-type' synthesis procedure for minimizing the l(inf) induced system norm.
