SUMMARY:

Linear matrix inequality formulations are an important tool to tackle analysis and synthesis of control systems, especially for uncertain systems represented by polytopic models. Linear matrix inequalities are successfully applied to robust state-feedback control synthesis. On the other hand, robust static or dynamic output-feedback control synthesis are more complicated to formulate as a convex optimization problem. Different strategies for obtainingLinear Matrix Inequalities formulations for static output-feedback control synthesis requires the calculation of specific parameters, scalar and/or matrix, which directly affect the performance of the resulting controller or even the existence of a feasible solution. In this work, optimization problems are proposed to determine these parameters, aiming to obtain the optimal robust static output-feedback control system for continuous-time time-invariant linear systems. An evolutionary optimization algorithm is selected to solve the proposed problem. It is presented case studies to demonstrate the advantage of combining optimization with LMI formulations.
