Abstract :
This paper is concerned with the mixed H2/Hcontrol problem combined with robust pole placement in linear matrix inequality (LMI) regions. Based on Differential Evolution algorithms (DEs), Salomon´s Evolutionary Gradient Search method (EGS) and LMIs, a hybrid algorithm is presented for numerical computation of a robus fixed-order, static or dynamic, output feedback controller. This approach does not require that all speciacations are enforced by a single closed-loop Lyapunov function. This allows to reduce the conservatism of the usual existin methods. This approach can be used for synthesis of reduced or full order controllers. Examples borrowed from the literature are discussed to validate this approach.
