Edvaldo Assuno*, Pedro L. D. Peres**
Resumo: | Algoritmos branch and bound so propostos para resolver os problemas de reduo H2 de modelos e reduo H2 da ordem do controlador, com condi\coes que asseguram a convergncia dos algoritmos para o timo global em tempo finito. Os limitantes inferior e superior utilizados no procedimento de otimizao so obtidos atravs de problemas descritos na forma de desigualdades matriciais lineares. Exemplos ilustram os resultados. |

Abstract: | Global Optimization Approaches for the H2-Norm Model Reduction and H2-Norm Controller Reduction Problems A branch and bound algorithm is proposed to solve the H2-norm model reduction problem and the H2-norm controller reduction problem, with conditions assuring convergence to the global optimum in finite time. The lower and upper bounds used in the optimization procedure are obtained through linear matrix inequalities formulations. Examples illustrate the results. |
Keywords: | Model Reduction, H2 Norm, Branch and Bound, Global Optimization, Linear Matrix Inequalities. |
