This is achieved by first replacing robust stability conditions which take the form of linear matrix inequalities with an algebraic Riccati equation that is parameterized by a quadratic separator. The synthesis problem is then solved with a DK-iteration type of approach, where alternatingly the controller and the quadratic separator are fixed. In the K-step a combination of Riccati solver and evolutionary search is used to find the controller, and in the D-step an LMI problem is solved for the separator. An advantage of the new method is that dynamic order and structure of the controller (e.g. decentralized) can be freely chosen. A numerical design example is provided to illustrate the practicality and numerical efficiency of the proposed method. © 2006 IEEE.enTechnikIngenieurwissenschaftenConference Paper10.1109/CACSD-CCA-ISIC.2006.4776744Other
