Abstract : This report describes accomplishments made in four areas of research related to robust, fixed-structure control system design and analysis: (1) the formulation of robust, fixed-structure control design problems in terms of a Riccati equation feasibility and the development of probability-one homotopy algorithms for its solution; (2) a comparison of descent and continuation techniques for H2 optimal reduced-order control design and an investigation of the best bases in which to represent the reduced-order controller; (3) the development of parallel processing techniques to implement probability-one homotopy algorithms for reduced-order H2/H infinity control design; and (4) the development and implementation of an object-oriented programming approach for the implementation of interior point methods to solve linear matrix inequalities (LMI's). Below, we motivate each of the four areas of research and briefly describe key accomplishments. The journal paper titles are used as headings and we list both the journal papers that have been submitted and the corresponding conference papers. Each of the journal papers is included in an Appendix.
